I don't know. Maybe the adults around me are lazy but literally all can't move out of comfort zone, start something new.
Since you mentioned, yes I'm trying to study abroad (and it seems very likely). And I should be, because it has been my dream since 14 or something. But I only started preparing last year. Why? I just didn't know I could study abroad. How could you be so blind that you can't study abroad is a valid question that I can't answer. I was misguided by all adults around me - just claimed it's not possible until masters unless you get into a few super-selective high schools. But I could probably just open internet and ask the same question instead of taking the words of people that can't even speak English. And I got confidence loss over not getting into these super-selective high schools (and not being able to study abroad), this effect combined with an unfortunate personal event got me into serious mental problems for around two years. This really wasn't "I didn't achieve good stuff because I partied too much" case, I didn't enjoy my time doing unproductive stuff.
I was lucky enough I realized this is not the case later on by some means.
Looking at the opportunities of those students studying at international high schools in my country (which I was able to attend, but didn't because I was not aware of the whole study abroad thing) who started this process 3 years ago and not 1 year, I'd probably get into Harvard or something of that sort - if I had these opportunities (which I could definitely have).
I just really feel far away from my true potential. I have huge regrets in non-academic areas of my life as well. I just didn't make the best decisions for myself.
And I'm scared of getting older because I see adults around me at 30s or 40s don't move an inch from their comfort zone. "I want to do x" "This would be nice" but there are no steps towards whatever they're thinking of. They just seem stuck. I'm not sure getting married or having kids is what actually causes this effect though.
It seems so real I'll study in the country I want to settle in, because I might think "nah I can't spend more effort moving somewhere else, I don't need more trouble"
