Go for it now. The future is promised to no one.
If you can dream it, you can do it.
To know oneself, one should assert oneself.
Always desire to learn something useful.
It's always too early to quit.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
Well done is better than well said.
I guess happiness is not a state you want to be in all the time.
