I have an opportunity to change careers. It will involve me resigning from my job and moving to New York City. Right now, I have it pretty cushy, in that I live where I grew up, where my family is, etc. I don't make much, and my job is a dead-end gig, but life's OK. With the summer, there are occasions to have a good life with sailing, good food, taking the motorbike out, relaxing, etc etc. With my current living arrangements, I'm alright for money. It's about money at this stage of my life, money trumps job satisfaction. Money, and quality of life, with one leading to the other. I've been living this life for the past 2 years, and then in April--I decided I coudln't go on like this, and I decided to make a career change. It proved easier than you'd imagine, than even I'd imagined, everything just fell into place like lego, everything is now set. I am scheduled to move to NYC next week to start a new field, in a new city, new everything. But I'm having trouble sleeping. Something in me is not altogether happy with this. I'm 30..everyone else (at least through social media) would be jumping up in cloud 9 when something totally new like this is happening to them. Not me. I'm nervous, my head is not working, I'm not thrilled....I'm nervous and scared. Is this just butterflies before my big change? Or does my subconscious, or whatever, know that this change is wrong--and therefore, holding me back? I am always chickening out before doing anything--everything from a vacation to a big project---but this is a life-changing decision, and there will be no turning back. Failure is not an option, in other words. How do I figure if it's just nerves, or if this is wrong? Some of the advice here from posters is quite insightful, so I thought I'd put my situation out here.
