To know oneself, one should assert oneself.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
It's always too early to quit.
After a storm comes a calm.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
Either you run the day or the day runs you.
Quality is not an act, it is a habit.
You always say 'I'll quit when I start to slide', and then one morning you wake up and realize you've done slid.
