Does any of you have any advice on how to get started on here,

I've been looking through the foundation courses but I'm curious, with all the techniques available and also theory side, how do people go about building a practice routine from the material on here, I'm trying to improve my theory knowledge and also build on some techniques I've been really sloppy on but I don't want to try and overdo it and end up biting off more than I can chew.
