Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
It's always too early to quit.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
Only the educated are free.
You never know what motivates you.
Either you run the day or the day runs you.
If you think you can do it, you can.
If you can dream it, you can do it.
Science by itself has no moral dimension. But it does seek to establish truth. And upon this truth morality can be built.
