What If (Hypothetically Speaking)

Think about this what if MLK would have giving up we probably would have never been consider equal, what if Micheal Jordan would have giving up he wouldn't be known as the best basketball player in history, What happen if wayne would have giving up would he have been known as the best rapper alive, what if obama would have giving up he wouldn't have made history as the first black president so hypothetically speaking what if I give up would I be stoppin myself from being something great??
