Isolation crafting

I’m trying to start a baby hat but can’t get it started for some reason! Also,SC, how do you get the tension right on your crochet, mine is far too loose.
You Tube is great, a lot of step by step instructions which you can rewind until you get the idea.

What’s your problem with starting you’re baby hat ? 
I don’t really know how I get my tension right     I just do. Probably just how my Nan taught me to do it (& knitting)
YouTube is great I wouldn’t be able to do most of the things I do without it. Especially as I can’t read crochet patterns. I am improving though I think I’d understand most of a pattern now. 
The magic ring/circle took me ages to get the hang of! I have to watch that video every time I start a project with one. There seem to be so many ways of doing a magic circle as well. Some make it look incredibly complicated     .
