To know oneself, one should assert oneself.
Do not weep do not wax indignant. Understand.
You never know what motivates you.
What you do today can improve all your tomorrows.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
After a storm comes a calm.
The most effective way to do it, is to do it.
When I was younger I probably didn't understand something basic about tact, but I think it kept faint-hearted people at arm's distance and that's not such a bad thing, because life is short and I know the kind of people I want to work with.
