Though once I got a 300% raise instead of a 5% one, would I really want to retire at the living standard I had before or after the 5% raise? So, chances are you are STILL not going to retire anytime soon...
I've had something similar happen to me (maybe not 300%) and I'm aware of the higher money but mentally I keep myself on my lower rate and standard of living, because I don't want to do this job forever. The sooner I can get to passive income funding an 'acceptable' life the better. Not everything that's worth doing takes money, just time, which you just don't have in a 9-5
