As for pride and arrogance let's not forget the following:
Narrated Abu Hurayrah:
The Prophet (sallallaahu alayhi wa sallam) said: Allah Most High says: Pride is my cloak and majesty is my lower garment, and I shall throw him who view with me regarding one of them into Hell.
[Sunan Abi Dawud]
It was narrated that Abdullah said:
"The Messenger of Allah (sallallaahu alayhi wa sallam) said: 'No one will enter Paradise who has even a mustard-seed's weight of arrogance in his heart, and no one will enter Hell who has even a mustard-seed's weight of faith in his heart.'"
[Sunan Ibn Maajah]
Second, you may forget to realize that any talent you have is purely from Allaah. So, when you really come to think of it, there is no greatness in us.
What comes to you of good is from Allah , but what comes to you of evil, [O man], is from yourself. And We have sent you, [O Muhammad], to the people as a messenger, and sufficient is Allah as Witness.
There isn't anything to show off. All good is from Allaah. Hence, we should praise Him and thank Him for the blessings He has given us so that He increases our blessings.
And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe.'
