What "wasting time" means? At the time we glorify self instead of glorify God, at that time we are wasting our time as... God is Time.
Do not allow anyone to continually act a fool in your life and reality revoke access to you, as necessary.
Don't focus on trying to be 'the best'. Focus on being irreplaceable.
As I said before, people really don't change. They only adapt until their needs are met.
