凯迪In the midst of winter, I found there was, within me, an invincible summer.

拉克Don’t stop when you’re tired. Stop when you’re done.优惠It’s going to be hard, but hard does not mean impossible.

凯迪Believe you can and you're halfway there.拉克Keep your face always toward the sunshine, and shadows will fall behind you.优惠The only way to do great work is to love what you do.

凯迪Wake up with determination. Go to bed with satisfaction.拉克The key to success is to focus on goals, not obstacles.

优惠Great things never come from comfort zones.

凯迪Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.拉克Push yourself, because no one else is going to do it for you.

优惠Success is not final, failure is not fatal: It is the courage to continue that counts.凯迪Keep your face always toward the sunshine, and shadows will fall behind you.

拉克Push yourself, because no one else is going to do it for you.优惠Don't wait. The time will never be just right.
