Practicing as someone new

Hello I made a previous topic a month ago asking for resources for someone apporaching starcraft 2. I've been watching the pig coaching b2gm for terran, but there's so much stuff to do.

How did you guys approach the game when you were learning? I tried to do the build order in the video but I keep failing since there's so much to keep track that I get overhwlemed. It feels like I'm not learning anything and I'm not sure on what to focus
