I tend to see delusions of grandeur meaning that you think you're of higher importance than others. That you are destined to make some profound impact on humanity that no one else is capable of. That you are in fact, God-like. But I hear you on the going nuts about spending big and making irresponsible decisions that get you into financial trouble. I'm not sure if that's from delusions of grandeur, but it is definitely a symptom of hyponamia/mania. I've worked for so many companies in the last 8 years. I've finally landed myself in a job that I feel really lets me use my creativity, most of the time. i get mad when I have to help someone grasp fundamental concepts, or spending time investigating bugs that turn out to be user error. But I was always jumping around, having that attitude that "This place is not good enough for me. i need to be somewhere where i can really deliver a high impact." i've finally reached that place. But I need to keep in mind that when things suck, I jut have to be patient and it will eventually turn around. i also have to be mindful of the fact that I have a great job, and nothing is worth doing something that was cause me to lose it.
