Carlos Castañeda said this quote

All paths are the same: they lead nowhere. ... Does this path have a heart? If it does, the path is good; if it doesn't, it is of no use. Both paths lead nowhere; but one has a heart, the other doesn't. One makes for a joyful journey; as long as you follow it, you are one with it. The other will make you curse your life. One makes you strong; the other weakens you.

Seek and see all the marvels around you. You will get tired of looking at yourself alone, and that fatigue will make you deaf and blind to everything else. - Don Juan

The trick is in what one emphasizes. We either make ourselves miserable, or we make ourselves happy. The amount of work is the same.

In a world where death is the hunter, my friend, there is no time for regrets or doubts. There is only time for decisions.
