Reading other comments, I see this amount would equal to 17 years of payments. There is no right answer. If it were me, I’d go for the lump, but I’m well aware that I am good at managing my own money in the sense that I don’t overspend, no matter what the bank account says. I’m naturally frugal.
I think the main considerations you need to take are: your personality, which you suggest you can’t trust yourself with that much money; on the other hand, the payee’s personality and the unexpected, ie., are they reliable enough to pay monthly or will they owe you? What if they die in a couple years? What if they go bankrupt? Etc. (not sure if there are system failsafes for these scenarios where you live).
I would suggest get the lump, deposit 80% of if or so in a fixed account with a high rate that won’t let you withdraw in a couple years, use the remaining 20% to keep yourself alive until you find a job. Once you get a bit more used to managing your own money you can decide what to do with the rest.
And the meme?
