Wow, congrats OP! Thanks for sharing your journey and your story. How many breaks did you take normally other than the vacation? I’ve been studying for the last 2-3 weeks non stop 8-10 hours a day and I will take a two day break this week. I can feel my energy slowly going down and want to make sure I can still learn new information. How did you schedule your breaks?
Nothing specific. I used to take a day break in the middle except from Set-Oct after my post vacation. If you feel exhausted, overwhelmed, bored, tired, its a sign that you have to take a break for a couple of days and come back again. I also followed this technique explained by byte by byte code - https://youtu.be/WVdNUFHnvJU to learn things in a productive way.
