How do you view yourself and what you have to give? We tend to look at others and what they have accomplished and downgrade ourselves. It happens no matter what we have done or what others think of us, and it can prevent us from doing what we can because we think we have so little. But I am reminded of the parable of the talents. You can read about it in the gospels, so I won't repeat it here. It makes the point that we are all given different levels of ability but all expected to use them wisely. It doesn't matter what you have as long as you are faithful in using it for the best.
This is regardless of what others may think of what you have - this is the essence of the song "In Whatever You Do" on my soundclick link. It was written in response to a discussion with someone at church who didn't think they had much to give ,or what they had wasn't seen as important (a christian artist). I told them, just be faithful in what you can do, and God will bless it.
