Let me ask you this:
What’s the point of spending hours upon hours in the practice room if you never perform?
It would be like spending years in medical school to become a doctor – and then never treating a single patient!
The whole purpose of investing all that time working on your musicianship is to share your music – and the enjoyment it brings – with others.
Performance is a skill in itself… and the only way to improve at it is to do it!
