Ask HN: Taking a sabbatical during a global pandemic?

I'm 27, with enough saved up for about 4-5 years of expenses at my current expenditure rate (8-10 years if I'm conservative enough). I'm considering taking a break from my job for a few months (maybe up to 1 year), and wondering how bad of an idea this is.

I've got a great job on paper. My boss is great — he's trying to help me grow and taking me under his wing a little. My pay is great and I get to work on stuff that impacts the world in a positive way, although only to a few users right now.

The problem is that I'm feeling very bored and unmotivated. I'm not sure if the career path I'm on is the right one for me long term. I think I might be suffering from burn-out and I'm not sure what to do about it. I'm worried that mentioning it to my boss would be basically saying that I can't handle my current responsibilities and that I should be given less of them.

My (probably naive) solution is to take a break from work after getting my bonus around November. I would like to use this time to learn, to workout, and to work on a non-profit project that I'm passionate about, but don't have the time for. I also just want to take a break from the corporate grind, and figure out what I want to do in the longer term.

Part of me feels like a fool for even thinking of this during a global pandemic. Another part of me, feels like I'm financially secure enough to take a break from the corporate world for at least a few months (accounting for ~3 months of job hunting).

How bad of an idea would it be to quit my job for a few months?

Are there any non-obvious risks I face other than just losing money and delaying career progression?
