Yes...
There was a point in time when I wasn’t happy with what I was doing, partly because I was burnt out and no longer had any interest in the job, or so I thought. I left the company only to rejoin it again a year later. The only thing I learned in that time was every job, career, occupation, and business has its own unique challenges and problems.
After I came back, not a lot changed regarding the actual job itself, except for my perspective and attitude. That shift in attitude/perspective ultimately lead to being able to develop better relationships, which allowed me to have influence, and better navigate challenges and problems.
I learned it’s not what you do, but how you do it. Most all of it had to come from within. Being able to get results made me happy and created less stress.
I literally came back doing the same core function as before, but those personal improvements helped me move up, and the job went from something I could not wait to leave, into something I can’t imagine leaving.
