Never complain and never explain.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Well done is better than well said.
Go for it now. The future is promised to no one.
Either you run the day or the day runs you.
Without hard work, nothing grows but weeds.
If you've got a talent, protect it.
Expect problems and eat them for breakfast.
I have a book coming out in September, for example, where the plot concerns counterfeiting, and I had to do a lot of research on that. Or on any legal matters, for example, I have to do a lot of research online.
