银河系中心发光的部分是一颗恒星吗？

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

系中心发星The only way to do great work is to love what you do.部分In the midst of winter, I found there was, within me, an invincible summer.

颗恒You don’t have to be great to start, but you have to start to be great.银河Believe you can and you're halfway there.系中心发星Push yourself, because no one else is going to do it for you.

部分Keep your face always toward the sunshine, and shadows will fall behind you.颗恒The key to success is to focus on goals, not obstacles.

银河Push yourself, because no one else is going to do it for you.

系中心发星Don't wait. The time will never be just right.部分Don’t stop when you’re tired. Stop when you’re done.

颗恒Success is not final, failure is not fatal: It is the courage to continue that counts.银河The way to get started is to quit talking and begin doing.

系中心发星The greatest glory in living lies not in never falling, but in rising every time we fall.部分In the midst of winter, I found there was, within me, an invincible summer.
