Everybody is good at something. There is that vacuum you were created to fill.
Before you were formed in your mothers Womb, God knew you and made adequate preparation for ur arrival on planet earth. He never sent any of us to this world empty handed. You gotta ask yourself what that productive thing is. That thing you never get tired of saying, doing or thinking about. That divine purpose is what makes each of us unique. No matter how insignificant you think that ability is, as long as you are passionate about it and also fulfilling divine purpose, it is bound to attract the Blessings of God. Once it has been discovered, then it is safe to say that uve passed the Passion Test. From there, every other thing becomes easier.
