Making a true decision means committing to achieving a result, and then cutting yourself off from any other possibility.
The only limit to your impact is your imagination and commitment.
Just because someone seems to have more certainty, doesn't mean they're right.
You can't influence somebody when you're judging them.
To measure success with material things is failure!
If you believe you are right, or you believe you are wrong, you're right. Whenever you are certain about it, you will support it. Remember that.
