I'd say that's ok if you have an end game/savings goal that sets you up for something better that isn't 10+ years out.I don't want to help derail the "Mental Health" thread by talking about judgements on people who live at home, but I'm going to do it anyway.
I have a colleague that has been teaching for about 10 years. He works at the high school he graduated from. He lives in his childhood home with his father and some random, CL room mates.
It feels super pathetic until I consider what his savings account must look like compared to mine. Then it's me that feels pathetic.
