Arrogance breeds arrogance!
Remember, the devil was thrown out of heaven for his arrogance.
Humble beginnings lead to great successes.
Never forget those who helped you on the way. They were gifts from God and if God can gift you then He can withhold it from you.
There may come a time where those same people who helped you need your help. If they turn to you then know that God chose you to be their gift. Don't throw away your rewards by shutting the door in their face. They will become someone else's gift and you will have passed on all your rewards. You don't want the door to be closed on your face on the Last Day.
Hurry to be that gift God chose you to be! :)
