All depends on your perspective, doesn't it?
Without a doubt you've done well to still be alive, if you count that as an achievement. Travelling around the world is definitely an accomplishment, yeah. Nobody would deny that. You're a decent, intelligent guy with some good values too, though the bragging maybe detracts from that in some people's eyes. I'm used to it so it doesn't bother me.
Most people don't get sectioned, even those like me who
are mentally ill and careless with the chemicals, so I don't know if that can really count. You must admit, though, that by some people's standards you've done a lot of damage to your body and your prospects over the years through your addictions. You're here in spite of your drug use rather than because of it. Wouldn't you agree?
