Time cannot be redeemed once it is wasted. Words cannot be unsaid once it departs from the mouth.
The philosopher Zeno said”Better to trip with the feet than with the tongue.” You can always get up after you fall, but what has been said can never be unsaid. Specially cruel and hurtful things.

One businessman was asked this question: 

“Mr. Businessman, how did you make your first successful million?

The businessman smiled and said, “One Dollar at a time.”

Don’t go for quick “jackpot wins.” There is no such thing as instant success. Long term success always involves process.
