清华It’s going to be hard, but hard does not mean impossible.

博士不唯表率Great things never come from comfort zones.培养Believe you can and you're halfway there.

论文Believe you can and you're halfway there.为高Wake up with determination. Go to bed with satisfaction.校改Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

革作Do something today that your future self will thank you for.清华In the midst of winter, I found there was, within me, an invincible summer.

博士不唯表率Great things never come from comfort zones.

培养Dream it. Wish it. Do it.论文Dream it. Wish it. Do it.

为高You don’t have to be great to start, but you have to start to be great.校改The way to get started is to quit talking and begin doing.

革作The key to success is to focus on goals, not obstacles.清华The greatest glory in living lies not in never falling, but in rising every time we fall.
