Nothing wrong with being comfortable where you are until something better comes along. And the definition of something better may be quite varied depending on who you talk to and their own circumstance.
You really never know how long your stay might be. I am sure a lot of "lifers" never thought they would be. Many of them may be quite happy and have no desire to go anywhere else. They have families, side businesses etc that keep them well occupied and the luxury of a great QOL and income that might meet or exceed any legacy career. Just saying.
