To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
Wherever you are - be all there.
The wise does at once what the fool does at last.
If you think you can do it, you can.
Always desire to learn something useful.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
The capacity you're thinking of is imagination without it there can be no understanding, indeed no fiction.
