Make Notes, Keep Them Organised 

This tip is one that I retrospectively wished I had listened to. 

Notes are the breadcrumbs along the path of where the knowledge is stored in your head. Sometimes you need to read through notes to resurface that knowledge. While you’re learning, create your own personal knowledge repository of notes, keep them clear and organised. If you’re aesthetically inclined, make them look nice and something you can be proud of. You’ll probably have to draw upon them a few times in your career, I know I had to rummage through boxes of old papers from my previous modules. I regrettably threw many of them out. Besides being useful, notes are a living record and a “horcrux” of the long hours spent learning your trade.
