My biggest mistake in life was thinking too big and aiming too high. Now I absolutely hate the saying "If you want to reach the moon, aim for the stars." This belief ruined me.

The people who were writing desperate emails and bending over to get a wage-slave job are much better off now.

Meanwhile I was trying to raise funding for big ideas from big investors; it was a complete waste of time.

Reality is "If you want to reach the moon, aim for the clouds." Then you have a better chance of actually achieving something, even if it's not your first preference.
