You can do it Phil.
Good luck going out there and meeting real people.
I understand why you have to cut back all the distractions to force yourself to get on with it.
Listen, don't bear it in mind the whole time that you have some shaking hands. My dad suffered from something similar his whole life. When he was little he could barely hold a pen and his handwriting has and is alway going to be shit.
However, he learned that he enjoyed carving and creating statues with stone. One of many hobbies anyway.
As you grow older I think you care less about the little hangups. The other people you speak to will have their own minor flaws. That's just human.
Good luck out there bro.
