难封Don’t stop when you’re tired. Stop when you’re done.背后You don’t have to be great to start, but you have to start to be great.

李广Keep your face always toward the sunshine, and shadows will fall behind you.难封Don't wait. The time will never be just right.背后It’s going to be hard, but hard does not mean impossible.

李广Don't wait. The time will never be just right.难封The greatest glory in living lies not in never falling, but in rising every time we fall.

背后The only way to do great work is to love what you do.

李广The key to success is to focus on goals, not obstacles.难封Do something today that your future self will thank you for.

背后Success is not final, failure is not fatal: It is the courage to continue that counts.李广Don’t stop when you’re tired. Stop when you’re done.

难封Great things never come from comfort zones.背后Your limitation—it’s only your imagination.
