It's always too early to quit.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
Only the educated are free.
The wise does at once what the fool does at last.
Either you run the day or the day runs you.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
By failing to prepare, you are preparing to fail.
Go for it now. The future is promised to no one.
I do believe that most men live lives of quiet desperation. For despair, optimism is the only practical solution. Hope is practical. Because eliminate that and it's pretty scary. Hope at least gives you the option of living.
