Why do people complain about life?

People complain about life because they don't realize what is life. They are not grateful because they are slaves of the mind, the mind that creates misery, ignorance, negativity and desire. But when people wake up to realize we are manifestations of the supreme. When we realize that we are the immortal soul, then our life is transformed, then we are able to live a life of peace and bliss and love as we count our blessings, knowing that we are manifestations of the Supreme. But till we live in ignorance, we will suffer, we will cry, look up in the sky, ask why, and die. Therefore, it is for us to be able to go on a quest, take the help of a Guru, an enlightened master, and then realize we are manifestations of God. God lives in the temple of our heart.
