<prompt> Human: I started my job in 2015, making 45K. Three years and a few promotions later, Im at 85K. My paycheck is nearly double what it used to be, Ive almost entirely avoided lifestyle creep, and the majority of that increase is going straight to retirementother investments. I still find myself feeling like its not enough. Like, Ill find myself scrolling through part-time weekend jobs seeing if theres anything I can pick up to pull down a few hundred more dollars a month. Theres no real reason for this- Im underpaid at work, but not severely, and I have no major purchases or life events Im saving forputting on hold because I cant afford them. Anyone else feel this way? What gives? How do you put those thoughts to bed?EDIT: Wow, this blew up. I couldnt possibly respond to every comment here, but Im trying to read them all. Thanks PF for the insights, good and bad. Its been a helpful read.  <response>: You could be suffering from a scarcity mindset and might find talking to a therapist helpful!! Your feelings are really common and its possible to work through them. Congrats on saying no to the lifestyle creep!!
