If you think you can do it, you can.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
I can, therefore I am.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
You never know what motivates you.
After a storm comes a calm.
If a weakly mortal is to do anything in the world besides eat the bread thereof, there must be a determined subordination of the whole nature to the one aim no trifling with time, which is passing, with strength which is only too limited.
