This problem recently hit me: I can cover my bills and necessities working ~1.5 months a year, and I can supply myself with all gadgets and other nice stuff I _want_ working ~3 months a year: I am frugal person, and I live in quite cheap part of the world.
I've built some wealth last years and now I lost all my motivation: it looks like the situation is in permanent libmbo, as it can't become much worse (it is too easy to keep things from falling apart) and it just can't become much better -- it seems impossible to qualitatively change my income level, so really expensive toys feel like in another world: why should you need to work hard 6 years to buy something if you may keep slacking and get the same stuff in 10 years?
Did anyone here fell into this trap? How did you recover?
You live in a cheap part of the world? What about spending some of that money to travel to not-so-cheap parts of the world? My best suggestion would be to take some time off to figure things out. And I mean real time off. Leave town, don't take your computer with you.
Also, given your frugality and the inexpensive standard of living in your part of the world, I'd say your experience is similar to those who have gotten FU money. I'd highly recommend reading this thread: "Ask PG & other successful folks: how did your life change after FU money?" [1] Especially read ttol's comment about mentally preparing yourself and the frame of mind required to handle FU money [2].
