Took a full week off from grinding and came back faster. Rest is not the enemy
I was doing leetcode every single day, streak in the double digits, and quietly getting worse: sloppier, more frustrated, dreading it. Finally took 7 days completely off. No problems, no tutorials, nothing. Felt guilty the entire time.
Came back and problems I'd been stuck on suddenly made sense. Turns out my brain needed to consolidate, not cram. If you're white-knuckling a streak and hating it, consider this your permission slip to stop for a bit. The streak is a tool, not the goal.
