Worrying is a waste of time. It doesn't change anything. It messes with your mind and steals your happiness. - Ziad Abdelnour

Start-ups fail for a lot of different reasons, but one I see repeatedly is ego. It presents as a dangerous sense of self-importance. Or the entrepreneur thinks they are the smartest person in the room who knows better than anyone else and either doesn’t seek out advice or doesn’t want to listen when it’s offered. Such know-it-alls delude themselves into thinking they have everything figured out, even though they don’t. For as hard as it is to elbow your way into the marketplace in ideal circumstances, it’s made exponentially harder when you don’t check your ego at the door.

Success is not found in what you have achieved but rather in who you have become

Too many people today on Wall Street go for the quick
buck at the expense of their reputation and client satisfaction, the
rationale being “let’s make the money while we can and retire early
in the sun.” For me, this is not a sprint but a marathon, besides the
fact that, in my definition, overnight success is 15 years. Anyone who
does not understand the basic tenets of this philosophy is not someone
I can or will do business with.
