Is it normal to risk losing my "rich" lifestyle to change careers?
I started out my working life doing what I was "supposed" to do. I got a bachelors degree and an MBA, then took a corporate job and am now an independent consultant. Even though I've never really loved what I do (sometimes hate it), I've done well and live what some would consider a "rich" lifestyle - big house, fancy cars, a big boat, money in the bank, travel, etc. etc.
But, for all of my life I've had an interest in another area (having nothing to do with my current work) and am just finishing up my Ph.D. in that area. Now, I would like to write books on the subject of my Ph.D. dissertation. To really make this happen in a serious way, I would need to work way less in my regular job, running the risk of losing all momentum in my consulting business. My income could go to zero for a long while and I'd have to sell some of my "toys", scale way back my lifestyle and live off savings. It's even possible I would discover that my gf was more interested in my money and leave me. I could possibly lose all of my material stuff. I'm middle-aged, so recovering from a stupid move could be very difficult at this point.
Honestly, having a much simpler lifestyle sounds very appealing. Most of my favorite things to do involve "getting away" and sitting by the water, having a beer around a campfire and other simple things. I feel like I've done the "material" thing and would be happier doing what I really love. Even if that means living in a van down by the river. Hopefully, I wouldn't regret the choice later.
So, is it normal to risk losing financial security to go for your dreams?
