Hey @BenMurph0205,
If you find it useful to make notes that you can refer back to at a later date, that is entirely your choice.
In the beginning, way back when, I wrote notes in a pad to refer back to, although I very rarely looked at them.
The process of just writing something down can help to cement the knowledge you are learning in your memory.
For you, because you are asking the question, I would say Yes, write some notes, you may be like me and not need them.
Every advantage you give yourself now will help in the long term.
Happy Blending!
