It's always too early to quit.
Never complain and never explain.
If you've got a talent, protect it.
I can, therefore I am.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
Either you run the day or the day runs you.
If you think you can do it, you can.
You just can't get too focused on worrying about what's going to happen in the next quarter. You have to worry about where the business is headed long-term.
