As-Salaam alaykum,
We read in ayat 156 of Surat Baqra (2:156) of the Holy Qur'an, where Allah Ta'ala says:--

"We belong to Allah, and to Him we shall return."

In this wise, we should realize that when we say: 'We belong to Him', we are declaring that nothing belongs to us-- nothing is deserved. Everything we have is a pure act of grace from Allah, the Generous. Once this fact reaches our heart, we will be able to break free from arrogance, pride and complaint.
