He will soon become so effective that some larger church will take him off your hands. A Pastor's job is tougher than most Christians can imagine. One of the greatest services you can do for God is to minister to your Pastor and his family. Instead, remember some specific point he spoke on and tell him how it helped you. When Pastor discusses a Bible verse during a sermon, TURN to that verse in your Bible.
Pastors love the sound of people flipping pages.
When Pastor makes a really good point, make a written note of it. If Pastor asks for a verbal response from the congregation, don't just sit there like a lump while silence reigns supreme. If a church usher or someone like that is absent or late, stand up and do the job. Don't wait to be asked. When a Pastor retires, he can't keep living in a parsonage.
