Should I accept a lower salary than I'm earning?

I think it's not pre-planning, like I want to have this thing. I know I have some baselines. I was in this comfort zone. I need this flexibility. I need financial stability. I'm expecting this much salary because I already have it. Once you move, you are on the top of the ladder, then you think, okay, I need at least this. If I get something additional, then I may consider other things, otherwise I'm in a comfort zone.
