Tuff question swan2020!
You know ... I think you are scared from this step; You want to do it, you have to do it; but you have a bad feelings!
Look swan2020 feeling that is a normal feeling everyone who is making a new step in his life or whatever (even if it's not big deal!) feels that ... For me; if I have something I want to do & I have to do at the same time then it's more than a raison which pushes me to do it! .. Do not get scared because it's something you wanna do! .. Like someone here said: Do what you like or like what you do!
Do not get confused! because feeling scared could hold you back & you get confused the point that you may delete eveything from your mind ! .. Just remember how much you want to do it & how cool it will be if you do it!
Be self-confedent & believe in yourself my dear .. Take it easy you'll find it easy!
