Not very specific question I should say, anyways these are the basics
evaluate what you are doing right now
analyze your strengths and weaknesses.
Make your strengths even more stronger and work on the area of weaknesses. Take up courses or educate yourself in those areas.
Affirm yourself everday with positive statements,nothing works like self affirmation.
work hard, be persistent , dont give up
you will definately be better than where you started
