I'm not sure it's possible to help given the information provided. You're asking how to stay motivated, but you haven't told us what it is that motivated you in the first place. If your only motivation all along was money and gadgets, then perhaps that's the root of the problem.
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].
I think you nailed it: I was motivated by the need for living decently. Now I climbed out of poverty and feel I have potential for much more, but don't have any particular challenge in mind to tackle, and have no idea how to find one: reached the Esteem step of Maslow's hierarchy of needs and stuck on it :)
