Believe in yourself all the time not just sometimes and when you find yourself slipping giving up not believing dig deep because someone has to believe in you and it needs to be you.
Be the person you can depend on; be the one person who never lets you down; be the one that makes a promise says they will be there for you and do it.
Make promises to yourself and keep them.
For me God has been a constant in my life; because I believe in him I believe in me. I am focused.
