What is my strength?

Have you ever wonder what is your strength?

This question was posted during last week life group.

Even though I was the second last to answer this question, I couldn't seem to get an answer after cracking my head hard..
All I could think of was..I DO NOT have one.
-I'm not creative.
-I'm not hardworking.
-I'm not determined.
-I'm not good at talking.
-I'm not careful.
-I'm not a risk taker.
-I'm not patient.
-I'm not very kind, very helpful. (I always have the selfish thoughts @@)
-I'm not a good organizer (even though I used to think so..perhaps there is never perfect planning)
-I'm not quick thinker/ responder.
-I'm not optimistic.
-I'm not good at music, arts, writing, cooking.

So...
What am I?
Good for nothing.
Good for all the weakness.
Gosh...I feel so weak, so small.

I hope the next time when I ask myself this question again.
I will be able to come up with an answer.
