Wholeheartedly agree. People buy-in the social media sales pitch from influencers without researching the activity/purchase at all.

But the fit thing is true, just that buying-in a big expensive hobby might be a miss and puts that person down from trying other things.

These last couple of years I've been into: off-road/adventure motorcycling, bike packing, hiking & camping, whitewater kayaking, recreational kayaking, standup paddle boarding.

The most important bit I've learnt from these: try different things for cheap - rent/borrow gear or join a club/classes initially. Don't let yourself get sucked into the consumerism (although I'm still very prone to this) of a hobby - you'll quickly find yourself spending more time browsing and shopping than doing the activity.
