Many teenagers and even as an adult struggle with low self esteem.
It is just because they want to be accepted by and fit in the society so desperately that they even ignore themelves.
Low self-esteem leads to a variety of problems regarding not valuing yourself, from aggressive behavior to depression to to teen pregnancy to substance abuse.
All in all you will lose more and more control about yourself and pass this control on to sombody else and ending up living somebody else's life.
The worst thing that can happen to you is that you begin to justify or make up excuses why you are in that certain position.
From the way I see it, being confident is believing in yourself that you can achieve anything if you set your mind to it and put all of your energy into something.
You have to acknowledge that you are worth being happy and being respected by others.
Most of the people see confident people both as arrogant and haughty but that is not true.
With a healthy self-esteem you are able to be successful and create a life that you want.
I hope many people get on the right track again and keep looking for the things which make them happy and treasure themselves
