I'm currently going through an elective year long break. There was no trigger - just thought I'd step aside for a while.
Its a good time to recharge and refresh - dabble with new ideas - train yourself for something new - speak with different folks - catch up with long lost friends - spend time with parents - shitpost on grapevine - you get the picture.
You of course need to be sorted financially to afford a break. If you have visibility of how long you can sustain your lifestyle and liabilities without wrecking havoc on your investment journey - strongly recommend a break.
Have some sketch of what you'd do with your time. It could be anything - you could take French classes, but don't not plan for being on idle for long. You shouldn't hit a wall in 15 days not knowing what you'd be doing in the break and then questioning the decision.
