The easiest and most reversible way to give your guitar a little flair without damaging the instrument itself, or spending a lot of money is to get a new pick guard with interesting colors, or to get a plain pick guard and decorate it with markers or paint.  On electric guitars, most pick guards can be removed with a small Phillips-head screwdriver, after removing the strings. Replacing it is as easy as placing it and replacing the screws. Pick guards are available at any guitar shop or music store. Acrylic paint and permanent markers are the simplest and best ways of decorating pick guards, and the bodies of guitars. There's more info about painting your guitar in the next section. Jerry Garcia used to stick a rose in between the strings on the headstock of his guitar, and a variety of little decorations hanging from the headstock or the tailpiece of your guitar can look pretty cool.  Try getting a few scarves or attractive looking scraps of fabric and wrapping them under the strings at the headstock, and knotting them tightly. Wrap some strings between the tailpiece and the strap of your guitar to keep it held in place. Another super-easy and effective way of decorating your guitar is to use a variety of stickers placed around the body of both electric and acoustic guitars. While some people think these negatively affect the tone woods and the resonance of the guitar, the difference is difficult to notice, and not significant on cheaper guitars anyway. All of the following make great guitar decorations:  Band stickers Bumper stickers Logos Stickers along the fretboard Leather strap with a psychedelic mandala? Lightening bolt? Bandolier of bullets? A cool strap can do just as much for your general stage presence and vibe as a cool decorated guitar. Shop around online for cool options, or consider making your own.  Adjust strap to an appropriate rock and roll height. That means low, if you're in a punk band, and nipple-high if you're in an indie band. Apply buttons of your favorite bands to the strap. This is also a good opportunity to rep independent record shops, bookstores, tattoo parlors, and head-shops in your town. Most electric guitars come with plastic toggle switch caps that you can remove and replace with any number of oddities, or leave blank for a more punk, or industrial look. Most knobs should have a solid metal inner knob that you can use by itself, or trick out with whatever you want to use. Pop the volume knob off your guitar and replace with a die that you've drilled a hole in, then glue it to the metal rod. Other cool options might include clay balls, lego men, or prescription pill bottles. "This machine kills fascists" was famously written on Woody Guthrie's guitar, and Willie Nelsons guitar Trigger is autographed by hundreds of famous people in marker. A few words can be a nice touch on a guitar, whatever message you want it to include. Use permanent marker, and make sure it dries completely before you touch it. It's very easy to smudge and make the smudge what's permanent.

It's important to choose a doctor whose expertise is suited to your problem. If you don't know any doctors or psychiatrists who prescribe medication for phobias, a good way to start looking is by contacting your family practitioner doctor. She will probably be able to refer you to a trusted colleague.  Realize that medication-based options will not solve the underlying psychological issue that causes acrophobia. But, it can make life much easier by easing your anxiety and allowing you to relax. Consider using alternative and natural medications/treatments. They could include acupuncture, meditation, or essential oils. Be sure to talk to your doctor before trying of these methods. Communication is key if you are seeking medication for your acrophobia. Describing your symptoms as clearly and thoroughly as possible will help your doctor make a decision regarding possible treatment options. Share your symptoms openly with your doctor and let your doctor help you. Not every doctor will be familiar with all of drugs that are available for treatment of acrophobia, so you may want to do your own research on these drugs. Share any concern you may have with your doctor and let your doctor provide useful feedback. Many drugs are reported to have negative side-effects. It's alright if you decide that these outweigh the benefits for you. Here are a few of the most common types of medication that your doctor might prescribe you:  Antidepressants such as SSRIs or SNRIs are drugs that typically act upon and increase the levels of certain neurotransmitters responsible for regulating mood. Benzodiazepines are fast-acting, psychoactive drugs that can be useful for short-term relief of anxiety. While effective in the short-term, benzodiazepines can be habit forming. Beta blockers work by blocking adrenaline. This medication is mainly useful for the relief of the physical symptoms of anxiety, such as trembling or rapid heartbeat. Though the cause of acrophobia isn't entirely understood, research has suggested it may be related to the way the body interprets visual and spatial stimuli from the vestibular system and eyes. For some sufferers, acrophobia may come from an inability to perceive visual and spatial cues at great heights, where the importance of such information is heightened. This may lead sufferers to feel disoriented or dizzy and incorrectly judge the positions of their own appendages.  In this case, acrophobia may have a physiological cause, rather than a psychological one, so talk to your doctor. You may be referred to a medical specialist who can give you insight into physical causes of your fear. In some cases, especially if traditional treatments aren't working, you might want to look into approaches that have been labeled “alternative,” “complementary” or “integrative.” These approaches are not for everyone, but they have been shown to be effective under certain conditions. These can include forms of treatment as diverse as acupuncture, mind-body centering exercises that increase the relaxation response, guided imagery to engage the mind in the healing process, and/or eye movement desensitization and reprocessing biofeedback. As with most practices, it’s always a good idea to consult a trusted physician before beginning any form of intensive practice.

Quantum superposition refers to the quantum mechanical property of solutions to the Schrödinger equation. Since the Schrödinger equation is linear, any linear combination of solutions to a particular equation will also be a solution of it. This mathematical property of linear equations is known as the superposition principle. In quantum mechanics such solutions are often made to be orthogonal, such as the energy levels of an electron. By doing so the overlap energy of the states is nullified, and the expectation value of an operator (any superposition state) is the expectation value of the operator in the individual states, multiplied by the fraction of the superposition state that is "in" that state.
