If you think you can do it, you can.
Always desire to learn something useful.
If you can dream it, you can do it.
The most effective way to do it, is to do it.
Without hard work, nothing grows but weeds.
It's always too early to quit.
After a storm comes a calm.
You never know what motivates you.
Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
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.
