The desire to improve your life is a stepping stone.  You also need to be open to changing how you think and feel.  To be willing to release negativity, dark or heavy feelings and events past, is part of the process of evolving into a better you.

1) Choose to forgive another person for what was committed against you.  If someone has irritated or harmed you, be willing to release anger that arises when you think about the person or situation.  As you let go of jealousy or resentment, you'll begin to sense what it means to be purified, uplifted and energized by love.

2) Choose to ask for assistance and expand on your emotional intelligence.  Its a question of recognizing you wish to better understand why you feel as you do in specific circumstances.  You can refer to books, participate in forums, meditate and consult experts.  Each method will help you shed light on "why?" and "what next?" 

3) Choose peace of mind in exchange for releasing negativity.  No matter what your current conditions, you always have choices.  These choices are limited or enlarged based on your mind and your expectations.  As you learn to see the positive, opposite feeling for each negative one that initially seems to control you, you also learn to temper intense or destructive feelings while you create serenity.
