Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.
There's a lot of stress out there, and to handle it, you just need to believe in yourself; always go back to the person that you know you are, and don't let anybody tell you any different, because everyone's special and everyone's awesome.
If you believe in yourself and have dedication and pride - and never quit, you'll be a winner. The price of victory is high but so are the rewards.
Believe in yourself, take on your challenges, dig deep within yourself to conquer fears. Never let anyone bring you down. You got to keep going.
Some people say I have attitude - maybe I do... but I think you have to. You have to believe in yourself when no one else does - that makes you a winner right there.
