Awesome! I like the skill-up trees. I think I will make one when I come to my next phase of learning Ultimate, going from 300–400 hours :D
It’s a great idea to take a note of all the skills you already have when going into a new skill, many of them can be used in some way.
Also, when you’ve practiced a skill for a while I think it can be a good idea to make a new tree/reassess the one you first made, to better figure out where to head next.
In the beginning it is easy to make progress in any skill, as there will be a lot of new things to learn, but later on it is easy to plateau and keep doing things you already know.
