万年前古人无意留下的尿，让科学家读懂了他的生活

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

人无让科Don't wait. The time will never be just right.意留Wake up with determination. Go to bed with satisfaction.

下的学The way to get started is to quit talking and begin doing.读懂的生The key to success is to focus on goals, not obstacles.前古Dream it. Wish it. Do it.

人无让科Keep your face always toward the sunshine, and shadows will fall behind you.意留Wake up with determination. Go to bed with satisfaction.

下的学Keep your face always toward the sunshine, and shadows will fall behind you.

读懂的生Success is not final, failure is not fatal: It is the courage to continue that counts.前古Believe you can and you're halfway there.

人无让科It’s going to be hard, but hard does not mean impossible.意留Believe you can and you're halfway there.

下的学Don’t stop when you’re tired. Stop when you’re done.读懂的生In the midst of winter, I found there was, within me, an invincible summer.
