Related: During solo travelling whenever a thought crosses my mind to do something and my instinctual internal response is discomfort, I try to make myself do it - even if I feel awkward inserting myself or going back.
I've had so many awesome conversations with random interesting people every day during my trips thanks to this. I've gone places I'd otherwise not experience, all for the sake of exciting adventure and pushing my own bounds. The confidence that comes from this is significant.
Also, as a former remote software engineer of 3 years, it has been so energizing to socialize with people again. Best upper that there is.
Solo travelling was how I formed one of my most salient memories of the "moat of low status", to wit: going to Japan in 2011. Japan is an advanced G7 country, but unlike most of the rest, very few people there speak or understand English. So I was put in the position of having to get by with my shitty Japanese, or attempt to communicate even more futilely with the locals in English and seem like an even bigger, more clueless asshole. I think I gained more levels of Japanese in those two weeks than I did in two years of university education.
There's a LOT here. I feel this applies to a lot of decisions.
For instance, if you want to make a product that requires a database and you like building database stuff, do the database stuff last. Do what is difficult first - fail fast.
The easy or default route will always be well known to someone.
