Your skills and your talents are not the same. Skills may come naturally or they may be acquired with work. Talents may come naturally to the surface or they may need to be cultivated and set loose.
Your needs are not the same as your passions. There may be some things that — if you don’t do them — you feel like the day isn’t complete. You may not like them and you may not want them, but you need them. Needs, I think, call out to you. Passions call out from within you.
I haven’t any idea whether talent and passion are critical ingredients in a good entrepreneurial life. Maybe skills and needs are enough. As for the critical ingredient in finding one’s vocation or “calling” — does it matter from which direction the call must come?
