I've been exploring the concept of past lives and reincarnation recently, so if you do get hit by a bus in this life, perhaps you can say to hell with the deposit in your next life? Should you remember anyway...
I agree on the time-tables idea dragline mentioned. To add to it, if you can find a way to make your current job enjoyable, AND you're working toward even more happiness down the road by leveraging the resources you're accumulating, you're in the clear. I try to think of it as what we would do if we could never retire (make our work life enjoyable to the best of our ability I imagine), except that we can, and in very short order.
I'd much much rather combine a high income job I like with microadventures early on and then have that money compound on my behalf throughout life by the salary class than constantly be worried whether my blog or vlog will produce enough income for me to continue my perma-travel lifestyle, or if I do get injured during the travels (like breaking a leg while hiking).

Oo, one more thing: delete the worst of social media (FB, Pinterest, Tumblr, Snapchat, Instagram) and go on outdoor or travel trips on evenings or weekends. This will help with not comparing your cube with the (usually indebted) 20-somethings in Paris or SE Asia. Let these personal experiences be your badass motivation to raise income/lower expenses, to the point where you're still happy anyway.
