Never complain and never explain.
If you think you can do it, you can.
Who seeks shall find.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
It's always too early to quit.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
You never know what motivates you.
Leap, and the net will appear.
There is as much wisdom in listening as there is in speaking - and that goes for all relationships, not just romantic ones.
