If you are stuck on one particular step, such as assistant trainer jobs … time to re-route without that step, still to the same destination.
What’s true is the “I” in “I am stuck”. “Stuck” is not a natural condition, it’s something we do to ourselves, mentally. Another term for “stuck” is “tunnel vision”. The situation is not the problem. Our approach to it is.
There is another way. Working that out is a lifelong career skill, and some people have it better than others. Those who aren’t adept at re-routing remain “stuck”, sometimes for years, sometimes decades.
You said you have worked with a career counselor for weeks. That should have helped … either not a good counselor, or what? What were you doing with the counselor?
I wonder if the jumping discipline schools us too much to take each obstacle in order. Career isn’t a course of Jump 1, 2, 3, and any deviation means losing. Career is Gambler’s Choice. Definitely have a plan, but if you miss a planned turn or if an approach becomes iffy, re-route … and keep going.
Also in this Gambler’s Choice, if you fall off, you can get back on and keep going. The course has no end, just keep riding.
There have been good suggestions in this thread and there will be more. Stop thinking about what is wrong with each one, because you attract what you hold in your thoughts. Of all the ideas that come your way, consider how you could make each work, tweak as necessary and pick the best one.
