Keep on working at it. We all have to work at getting gold in this game.
Even the highbies aren't all "rich". Some may be, but there's a lot out there working hard to get the gold they need for each new skill (my last bunch was an average of 400g EACH) and new weapons and armors. Just keep at it; you can do it. There's a lot of threads on how to make money in the game. Try doing a search. I'd write it all out again, but I'm sitting here staring at the computer like a zombie because I can't sleep.
