Need more tips for making snake less afraid

[Homebody]

Hey it's me again. My mission is to get my ball python to a point where he is not afraid of handling.
I am already using a pillow case for him to hide when he is oout and it seems he does get a little more mellow when he is inside. But I am not sure this will be enough since I encounter the same kind of problem again. When he doesn't want to come out I have to go in there and get him out (gently). And then I am reinforcing his fear again. I have to admit I am kind of tired and am losing my patience.
It feels like I am doing something we both don't enjoy. He doesn't want to be afraid and I don't want to make him afraid of me.

It's a worthwhile goal to teach your bp not to be afraid of you, but to enjoy handing may be asking too much. My bp never enjoyed handling, he tolerated it, sort of. During a typical handling, I would remove him from his enclosure and put him on my shoulders. He would slowly try to get down. Just before I felt he was going to fall, I would put him back on my shoulders. Over and over. If I sat while handling him, he always tried to get away. He didn't leave quickly, but slowly. He didn't seem afraid of me. I think he just preferred being someplace else. So, I let him go and got my enjoyment from watching him; trying to predict where he would go and why. I was somewhat surprised to discover that I enjoyed this more than handling.
