I'm not sure where to post this so I decided to post it here.
Here's the problem: I don't know how to type properly. I type looking down at the keys and I use only three fingers.
How many of you know (or not) how to type?
Is this going to be a huge problem?
I feel like it's too late for me to learn, and now I'm kind of embarrassed about it.
I never had proper training...

I'm only on the first draft and my wrists get tired easily.
What are some tips to improve?
