I, Me
A leader of business? Ha! That's me! That's I!
This version of I is more boyish. It's a sort of young man/boy way of saying "I," though you'll hear women use it too sometimes (it's a teensy bit tomboyish though).

You use the word I a lot. You say it so much, you just start referring to yourself with the french beaucoup (ぼく) for a lot. Because you love yourself a lot.
I am beaucoup I am. (Is that a pun? Did I do it right?) I dunno. Just say ぼく a lot and try to connect all of your approximate knowledges of languages together. Merci ぼく from ぼく.
