A sense of entitlement can hinder the very progress you need to get to where you need to be. No one is saying you have to feel worthless but humility goes a very long way to preparing you for the big leagues. Do not be angry at life when thingsdo not go your way. If they always did, you would be spoilt and more than likely not self-sufficient in most regards. Your blessings will come, some will take longer than others.
