The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
You never know what motivates you.
It's always too early to quit.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
To be a good loser is to learn how to win.
After a storm comes a calm.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
People are at their happiest if they are true to themselves. I think that applies to their chosen profession, friends and relationships. It goes for your health too. If you are true to yourself, it seems to me everything should work out pretty well.
