If you think you can do it, you can.
It's always too early to quit.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
Well done is better than well said.
I can, therefore I am.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
Frankly, the reason I joined MENSA is because I was dating a guy at the time who spoke five languages and could solve a Rubik's Cube literally with his eyes closed because it's just an algorithm.
