It's always too early to quit.
Do not weep do not wax indignant. Understand.
Never complain and never explain.
What you do today can improve all your tomorrows.
You never know what motivates you.
Either you run the day or the day runs you.
Wherever you are - be all there.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
I can, therefore I am.
If global cooling will come soon - scientists will lose trust.
