A 2 year old cannot recognize the boundaries between appropriate and inappropriate behavior unless you spell it out for them in their language. Keep the rules straightforward and essential, focusing on safety and respect for others. For example:  “You have to stay buckled in your car seat to be safe in the car.” “You can't take a toy from someone without asking because it makes them feel sad.” “We don't hit when we're upset because it hurts the other person.” This will reinforce the limit and help them understand it. Whenever it's time to present a new rule, or remind them of an existing one, say something like “I'm going to tell you our rule about sharing and I want you to say it back to me.”  Depending on their communication skills, it's fine to help them through repeating the rule. If they're distracted or aren't interested in taking part, wait until their attention returns to you, then say the rule again and have them repeat it. You can often turn this into something that's fun, as opposed to a chore. For example, you could create a habit of together saying "we always hold hands when we cross the street" anytime you walk up to an intersection. If you won't be willing or able to stick to a rule in nearly every instance, it's usually better never to make the rule at all. A 2 year old won't understand how a rule can be important if it isn't enforced all the time.  For example, your 2 year old won't understand the point of "no standing up in the bathtub" if you let them get away with it once in a while. If a rule needs to be changed or dropped, explain why in simple terms: “Now that you're bigger, you can stand up in the tub, but only when it's time to rinse off and get out.” Consistency reduces the feelings of “What's happening now?” and “Why are we doing this?” that can fuel resistance from toddlers. If, for example, you create a bedtime routine that starts at the same time and follows the same process every night, there will be less reason for the child to argue about it. Never miss an opportunity to praise them for good behavior. If they share a toy, say “Great job sharing, Ben!” If they stop playing without a fuss when you tell them it's lunchtime, tell them “Thanks for putting your toys down so quickly and coming for lunch.” For 2 year olds, positive reinforcement—praising good behavior—is more effective than negative reinforcement—punishing bad behavior. They crave your attention and approval, and will learn to act accordingly in order to get it. You want to model appropriate behavior, which means keeping your cool even when something—like a misbehaving 2 year old—is frustrating you. Instead of shouting “Stop it!,” take a step back or turn away, breathe deeply a few times, and speak calmly but directly: “Tommy, you can't swing that around because you'll hit someone with it.”  Spanking or other physical punishments aren't effective with small kids, in part because they'll struggle to connect it to their own actions. This is especially true if you spank them while you're upset—this tells them that anger and violence are appropriate responses to being upset. Make sure to get down on their eye level, remind them of the rule and why it exists, and have them repeat it back to you to ensure they understand. Do this right away. Don't wait to talk to them.

Article: You don't need to tear through several newspapers per day, but having a basic understanding of what's going on in the world will give you a reputation of being smart and knowledgeable, both of which are attractive qualities. This process can be as simple as going on Google News and reading two or three of the biggest stories each day.  You don't have to sound like a know-it-all to bring up something interesting and relevant. People will think it's cool that you have time to think about the world -- not just yourself. If you have no idea what's going on in the world, you'll look clueless -- and that's just not cool. Whether you join a club at school or take a screenwriting class in your community, doing something that you love will not only make you more interesting, but it can help you make new friends. Don't be shy about pursuing your interests, even if some of the things you love may not be traditionally considered to be "cool." If you join a club, you can eventually have a leadership position in the organization, which is very cool. The more you can do, the cooler you'll be. Learn how to fix a car, build a table, finish a deck, or even to cook the perfect steak. If you have a skill, you'll not only be useful to others, but people will think it's cool that you took the initiative to do something. Once you've mastered a skill, you can even teach it to someone else. Now that's cool. Though certain interests, like team sports, can be developed better in groups, part of being cool is being able to spend time learning things on your own. Anyone who is comfortable spending time by himself and who even likes spending time by himself is much cooler than a person who is so socially eager that he's desperate to always be hanging out with people.  Spend time learning to play the guitar, picking up a new language, or just writing down your thoughts in a journal. This will help you figure out who you are and you'll become cooler in the process. If you're always around, people will take you for granted. But if you're sometimes busy because you're catching up on some alone time, then people will appreciate you more when you're around.
