It's always too early to quit.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
Begin to be now what you will be hereafter.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
Leap, and the net will appear.
Without hard work, nothing grows but weeds.
Never complain and never explain.
The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be.
