If you think you can do it, you can.

Begin to be now what you will be hereafter.

Go for it now. The future is promised to no one.

The wise does at once what the fool does at last.

Know or listen to those who know.

If you've got a talent, protect it.

It's always too early to quit.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.
