I, me, and myself. Who is more important?

Well these all are relative concepts.You just cant segregate any of them.Its better we give importance to the correct word that matches the grammar for the sentence.In general all the three are important.

I agree with the person above me. I also think that maybe if you broke it down in to terms of id, ego and superego then you might be able to make a better distinction of what type of self is better to portray....
And yes there is strength in numbers and when people come together for a common cause things get done a lot faster
