A string of successes can kill you if they make you think, 'Hey, I'm smart; I can't make any mistakes'.

We start out as pretty creative beings... Children let their imaginations take them to place they've never seen and do things that seem impossible. We encourage it as fun and playtime, but we should celebrate it as the potential for great discovery and accomplishment.

As you schedule individual tasks, give yourself a cushion. Mark the due date a few days ahead of the actual deadline so you have time to deal with changes or last-minute emergencies.

A great accomplishment shouldn't be the end of the road, just the starting point for the next leap forward.

I've known entrepreneurs who were not great salespeople, or didn't know how to code, or were not particularly charismatic leaders. But I don't know of any entrepreneurs who have achieved any level of success without persistence and determination.

If you want to stay youthful, stay useful.

Never buy anything in a room with a chandelier.
