人无让科Your limitation—it’s only your imagination.意留Push yourself, because no one else is going to do it for you.

下的学Push yourself, because no one else is going to do it for you.读懂的生Push yourself, because no one else is going to do it for you.前古Dream it. Wish it. Do it.

人无让科It’s going to be hard, but hard does not mean impossible.意留Dream it. Wish it. Do it.

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

读懂的生The way to get started is to quit talking and begin doing.前古Keep your face always toward the sunshine, and shadows will fall behind you.
