周天The key to success is to focus on goals, not obstacles.

设需种Great things never come from comfort zones.避免Keep your face always toward the sunshine, and shadows will fall behind you.

问题The only way to do great work is to love what you do.周天Believe you can and you're halfway there.设需种It’s going to be hard, but hard does not mean impossible.

避免The way to get started is to quit talking and begin doing.问题Don’t stop when you’re tired. Stop when you’re done.

周天Wake up with determination. Go to bed with satisfaction.

设需种You don’t have to be great to start, but you have to start to be great.避免Wake up with determination. Go to bed with satisfaction.

问题Push yourself, because no one else is going to do it for you.周天The way to get started is to quit talking and begin doing.

设需种Believe you can and you're halfway there.避免Keep your face always toward the sunshine, and shadows will fall behind you.
