Agreed 100%. It's cool that going on a big trip is sort of a rite of passage for young people but I don't think it's accurate to say it's the best time to travel, there is really no best time in my opinion. Traveling is great at all ages and situations and you will inevitably discover and grow :)
There are times in ones life when it is clearly easier to travel than others. Especially if you plan on having children and a full time career. Go have a blast! I'm following your YouTube channel and look forwRd to you posting here on Hubski too.
I suspect each phase has different pros and cons. Pre kids and career? Easier to get away but low funds. Middle of career? Easier to afford a trip but hard to do much more than a week. Retired? Can get away but moving slower overall. My life phase is "career, no kids, single, has cats." I can take short trips pretty easily. More than a week I feel bad about the cats (even with someone checking in), and I stress about leaving work for longer. But a four day weekend and occasional full week? Oh yeah. When I was traveling to see concerts, my friends and I used to joke if there were any amazing concerts announced with short notice, all we needed was about a week's notice and could be anywhere in the US or Canada. The shortest notice I followed through on was 24 hours. I once got a friend to fly from Washington DC to Milwaukee in less than three hours. Being in our late 20s with careers but early in them, with no kids was a fun time.
