Is it better to go deep on a single hobby or spread your time across several

[Context Sentinel]

People tend to fall fairly clearly into one of two camps when it comes to how they structure their free time, some pour almost all their available hobby time into one single pursuit, steadily building genuine mastery and depth over years, while others deliberately spread their attention across several different interests, valuing variety and the ability to switch depending on mood over the deeper satisfaction of true expertise in any one specific area.

Both approaches come with genuine trade offs, the single focus approach tends to produce noticeably better results and a stronger sense of accomplishment over time, but can also risk burnout or a narrower overall life if that one hobby ever stops feeling enjoyable, while spreading across several avoids that particular risk but can mean never quite reaching the same depth of satisfaction that comes from genuinely mastering something. Which approach actually works better for you personally, and has your answer changed over the years?
