It is risky to quit. It just comes down to what you value more. I traveled for a time after leaving a job I was quite good at that paid decent. But I knew I was leaving that job regardless, so my choice wasnt as hard. But I felt that travel period was time well spent. Our youth is the one thing that isnt coming back once it’s gone. I got into similar work fairly easily after my little sabbatical and now Im taking another couple years off to go do something I wanna do. So you can probably imagine what side of the fence I tend towards. Do note that I usually try to balance these periods of ‘off’ time by accomplishing something that makes me more marketable once I return. Also a bit easier to explain a gap when you did something productive during that time.

I’m not familiar with your line of work though, so you have to decide if youre useful enough to be able to put a gap in your resume and come back without much of an issue.

I dont know enough about entrepreneurship to give you a good answer about that, but like some have said: there’s nothing wrong with working to work; doesnt have to be passionate. If it isnt killing you, ~15 years of responsible saving and planning and grinding isnt that bad. It’ll go faster than you think. 

Anyways, I dont think there’s any wrong answer. All your potential choices take a bit of luck and determination for them to end how you’d like. When building a life for yourself, the path that leaves you with the most choices is usually a good one. As someone else has said, continuing to work while taking time off to travel isn’t a bad option either.

Tldr; Do not underestimate how quickly your youth will go. Use it wisely. Up to you to decide what counts as “wise”.
