Weighing too much on someone's talent and not someone's personality. I think it matters whether someone has a good heart.

Focus on something that has high value to someone else, be really rigorous in making that assessment, because natural human tendency is wishful thinking, so the challenge to entrepreneurs is telling what's the difference between really believing in your ideals and sticking to them as opposed to pursuing some unrealistic dream that doesn't actually have merit, be very rigorous in your self analysis, certainly being extremely tenacious, and just work like hell.
