Self-centrism, while no doubt obstructive in the search for a cure to cancer can be quite useful when say, asking for a raise or deciding whether to ask that girl out.

I find it quite useful, when unsure about something, to assume the option that is most beneficial to you.

This positive self-centrism could also come in quite handy when starting a startup.
