1 Peter 4:10-11 teaches that: We all have gifts; they are intended to serve others; we must steward them well; and they are for God's glory. Also, we see in 1 Corinthians 13:1-3 that love is above them all, and in Philippians 2:2–8 that we are to have the mind of Christ (perfect humility) in all we do. Gifts are given "for the common good" (1 Corinthians 12:7) and are meant to build up the church in unity, maturity, and love. If you don't know your gift(s) – ask God and the people around you, and then use them for his glory!
