How do you identify your gifts?
Ask yourself what you enjoy and what you are good at doing. When you use a gift you become better at it.
If it is hard to evaluate yourself, pay attention to what others say about you. Unless they are flattering you, what they say you're good at is probably the way you are gifted.
If you don't remember anyone suggesting your giftedness, ask someone you trust. "I want to help others and I'm trying to figure out what gifts God has given me. What do you think is my gift?"
Most importantly, pray for God to reveal it to you. Listen to what He says and watch where He leads you.
Spiritual gift tests can help you determine your gift.
