We need to be clear about why we are serving as part of a Church.  

Some people serve to use their gifts to the glory of God.

Others serve because they have a gift and enjoy using it.

Both groups are part of the Church, and most of the time, I cannot tell the difference by watching. Deciding on your motivation requires some soul-searching and prayer. Ultimately, it is between you and God, but it is an important question to consider.

One leads people to praise God, and the other to praise you.
