If you think you can do it, you can.

I can, therefore I am.

If you can dream it, you can do it.

To know oneself, one should assert oneself.

You never know what motivates you.

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

Either you run the day or the day runs you.

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

Problems are not stop signs, they are guidelines.
