Seriously though. I believe self improvement starts within yourself, a change of life style and mind set, one compliments the other.

Make a conscious decision to change your life, you have got to want to do it otherwise you will fail, like giving up smoking, if you try to give up to save money, you will fail, you will never give up, your not in the right mind set, you need to hate it.

Join a gym, excersise
Change your diet
Focus on a goal.

Once you see the results happening your frame of mind will change and you will become more motivated and focused and your confidence levels will rise as you feel better about yourself and whats around you.

But it all starts with the right state of mind to give yourself the push.
