Never complain and never explain.
Things do not happen. Things are made to happen.
Always desire to learn something useful.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
You never know what motivates you.
If you can dream it, you can do it.
The capacity you're thinking of is imagination without it there can be no understanding, indeed no fiction.
