To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
Either you run the day or the day runs you.
Know or listen to those who know.
Always desire to learn something useful.
Well done is better than well said.
Who seeks shall find.
I've learned to think in terms of having a long career. Actors can have very long careers that last until the day we die, but there will be moments when you'll feel like you're a failure or when you're disappointed in yourself.
