Understand their personality
While it is good to treat a teenager like a teenager, but every person has his/her own personality and traits. Sometimes it gets difficult to get along with a teenager because you do not understand his/her personality and get everything messed up.
Teenagers are not adults; their hobbies and ambitions certainly don’t match yours. So, understand what their taste is and how it should be handled. Ask about their interests and aim of life and take your time in understanding them.
Teenagers, who are headstrong, will probably give you a hard time, but they can become really intimate if you do not restrict them from living a life they want. You can gradually make them change their life style and get along with them.
Just be casual. If you are a teacher, do not sound like a teacher in front of teenagers - you will probably make them hate you. Being casual means that you do not get into too much formalities and you can have fun when you want to.
Talk about things that interest them
You can get along well with a teenager(s) if you know his/her interests. Ask them what they like and try to talk to them about it.
For instance, if a teenager you are dealing with likes to watch movies, you should also get yourself familiar with the latest movies. Discussing the interests will help you get close to them and you can gradually influence them.
Do not impose your thoughts on them
Remember how you felt when you were their age and someone wanted you to change your lifestyle abruptly. It was a hard thing at the time, and it is still a hard thing right now. So, do not fool yourself into thinking that lecturing a teenager about something excellent will reap results. You will probably alienate them with your heavy handed tactics. Go easy and have a discussion with them on a regular basis.
