Yes! The most important bit of this comment IMO is the "about two weeks" part. There's a trough of uselessness in vacations – 14-21 days is the minimum in my experience.

In week 1, I'm annoyed by my vacation. I don't care about sitting on a beach, I'm bored, I want to get back to solving problems.

In week two, I'm aghast at the mundane routines I've fallen into, bullshit hangouts, errands, and reddit.

Something weird happens in week 3 where all the books you read, all the ideas you have, start to take on this new lightness and optimism and interestingness. Hang out in that vacation mode for as long as you can afford to.

I wish I had more insight into that last state, but it's a very rare day that I take more than a month off work.

For me at least, vacations under 3 weeks are somewhat useless from a "recover your health" standpoint, and I'm much better off spreading a week or two of vacation around in a way that makes many 3 day weeks, giving room to run errands and make non-work life more relaxed across the board, rather than oscillating between tire fires and mandatory relaxation.
