Article: Novices can make critical, rocking-out-impairing mistakes. Before you have the time of your life, you must be fashionably prepared.  Opt for the metal t-shirt. This DOES NOT MEAN the t-shirt you bought at the merch stand. Oh, no, no. Find your Pink Floyd: A Momentary Lapse of Reason Tour tee (even if there are armpit stains) and mount the floor section with pride. You'll be the guy in the sweet t-shirt with cred and mystique. The louder the better, generally. Stick to the same genre as the artist you're seeing. If that's not an option, bands such as Iron Maiden, Judas Priest, Pantera, Guns and Roses, Ac/Dc, The Doors, Motorhead, etc. are a safe bet.  Don shorts or pants. If you'll be in the pit, you'll get sweaty, sticky, and hot very quickly. Keep this in mind. Wear sturdy shoes. Let me repeat: WEAR STURDY SHOES. Do you want a bloody toe? Because your feet will get stepped on. Tennis shoes are okay, but leather boots are better. Keep your hair out of your face. You'll be glad you did when the sweat is pouring down your brow. What's more, don't use dyes. Being one of 1,000 people with pink running down their faces at a Gwen Stefani concert is not what you're aiming for. Girls: the same things apply. DO NOT wear a skirt. It may get torn. This means a bit of money, chapstick, keys, ID, and, of course, the ticket. That last part is pretty important. You'll be in a crowd of a zillion people. Make sure your belongings are secure. If they're not, they may get lost or stolen. If your front pockets aren't big or safe enough, get a small bag to put under your t-shirt. A camera may or may not be allowed. Check the ticket for details. If it's not, leave your phone in the car or at home. It's rocking out time. The time we've all been waiting for. Take cues from the crowd if you're unsure or rock out to the beat of your own drummer, so long as he's keeping time with the one onstage.  Master the head-bang and surging rock hand-gesture (metal horns). Along with jumping (which you can presumably already do), these are the fallbacks in any mosh pit. Place your index and ring finger in toward your palm. Raise your hands in the air like you just don't care accordingly.  Keep an eye out for crowd-surfers. They're probably not concerned about keeping their elbows tucked. It's best to only become one of them if you're in a big group of people who literally have your back. Otherwise, you may get dropped, lose a contact, and get your wallet stolen. Get close to the stage! The closer you are, the more hypnotizing the feel. Don't shove your way forward inciting irritated looks from those around you--but if you see a path, go for it.

Choose your attire wisely. Carry only what you need. Get on the floor.

Don’t spend all of your time outside of lessons making fully personalized lesson plans—instead, set up a lesson plan system and tailor it to your students as you learn more about them.  Have a library of materials such as chord handouts, songs, commonly used scale sheets, blank chord grids, and a set of fallback lessons.  Organize your system based on skill level. Teach your students some tips and tricks at the beginning to help them see progress early on. This will encourage them and give them the confidence to keep taking lessons.  For example, you could teach students basic scales so they can practice making up solo parts. You could also teach them a famous riff or the chords to their favorite song. Think of songs and riffs that people would play in a guitar store while checking out the guitars—songs that sound cool, but are deceptively easy. Group classes will cut down your hours and help you earn more money. A good group size is about eight people—with this number, you can make some extra money by charging per student, and you’ll still be able to give each student some one-on-one instruction.  Group lessons usually last forty minutes to an hour. Depending on the age range of your students, you may want to adjust the time for their attention span. Younger children tend to need breaks or shorter lessons. This style of class has a very different dynamic and may take some experience to master. Students may move along at different paces and become frustrated. Group classes generally work best for beginner or intermediate skill levels. Putting together a recital is a great way to motivate students, give them a goal to work towards, and reward them for their efforts. It also lets parents see what they’ve been paying for.  Tell the students about the recital several months in advance. Give them one or two songs to prepare and perform at the recital and consistently work on those songs with them. Invite your students’ families and tell students they can bring friends and extended family as well. Prepare some refreshments or ask parents to contribute some refreshments such as cookies and fruit beforehand. School auditoriums, churches, and senior centers are great location options for a recital. If you’re having a  hard time finding students in your area, try teaching through Skype. You can also use Skype when you take vacations or travel to maintain your current client base. Many guitar teachers feel like they can’t take a break or travel, so this is a great option to utilize. One downside to a career in teaching guitar is its unpredictability. Sometimes factors such as lesson cancellation, student turnover, and holiday lulls may mean that your income fluctuates from month to month. Start thinking of ways to supplement your income.  One option is to pre-record your lessons and then post them online and sell access to them. This will give you passive income and if it works, it will cut down the amount of time you’ll spend giving live lessons during the week.  You could also look for a part-time job as a contract guitar teacher at a school or college.
