At some point I got married and eventually had kids after which these kinds of romanticized ad-hoc adventures became impractical. Sometimes I wish I'd been more focused when I was young. I feel like I probably wasted a lot of time pursuing ideas that had a high risk of not being sustainable for the long-term.
I find myself giving younger people advice that I would have balked at at their age. They don't listen to me of course, just like I didn't listen to more experienced adults when I was in their place. No one wants to be told, "Don't follow your dreams. Weigh the risks and the potential return on investment first". I guess part of being young is taking those risks and learning from your failures. And sometimes, chasing an impractical dream pays off. Sometimes they pay off big.
But now days when I get the wanderlust or some feeling of discontentment and find myself wondering, "there must be more to life than this?", I just try changing something small in my routine, like, "you know what? I think I'm going to start taking walks during lunch every day.", or, "I think I'll study this new language for an hour every night after the kids go to bed.", or, "I think I'll build a garden enclosure in the backyard". I often find that by changing something small in my routine, I can break out of the monotony and feel some sense of accomplishment I hadn't noticed was missing.
But even then, there is still some voice in the back of my mind that says, "someday, when the kids are old enough and out of the house, I think I'll take one last big risk and embark on some kind of unlikely adventure."
