If you have a career then there is a time when you don’t have it. Same for a future. If you have anything, then it’s yours. Your career isn’t yours nor is the future. You are just doing something at the moment.
You are just nowing. If you can just accept what you are doing at work rather than look to what comes next you have more chance of enjoying what you are doing instead of running away from something unpleasant or moving towards something considered more acceptable.
Can you accept your career/job at the moment? Can you accept your present without wanting to move away? Careers don’t come to an end. What you are doing might end and then you do something else. If you focus on the present moment your career will last as long as you do. You might even create a longer now if you enjoy yourself.
I meet so few people who enjoy their jobs/careers/lives. They seem to be hurrying to something else and missing what is happening now. If you want to have something. You do. You have now. Everything else is past or future.
