Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
If you think you can do it, you can.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
The dog that trots about finds a bone.
It's always too early to quit.
Things do not happen. Things are made to happen.
Seeds of great discoveries are constantly floating around us, but they only take root in minds well prepared to receive them.
