for 4 years Ive been obsessed with ISK maximization/optimization, and you know what, I felt so poor. Ironic huh? I acquired more billions that I would ever need.
now for the last couple of months I tried a new approach. I would just have fun doing whichever I wanted to do. Even I started manufacturing my own ships, just for teh lulz, even when I know getting them on the market is quicker and less expensive (morons selling under manufacturing costs always kept me ahead of manufacturing). But who cares? I am manufacturing my ships and enjoying the process.
Same goes for everything else. As a former ISK-optimizer I was an extreme carebear, a highsec dweller, never undocking when wardecced, etc. NO MORE! I enjoy traveling trhough lowsec, sometimes just exploring the galaxy for fun. And teh thrill when theres a gate camp and you manage to escape. Yay! Sooner or later you get exploded, but who cares? You have lots of billions. Some killboards will tell the world you failed. Well who cares actually?
TLDR: stop thinking of ISK. Money is important in real life, not in a videogame. This is not a second job. Start enjoying EVE Online!!!
