When people change roles or jobs, sometimes they don’t realize what have they gained from the job. ‘Career experience’, ‘Job experience’ or ‘role achievements’ etc. may not be the best terms/frames to describe what you gain on the job.
I believe, we build ‘human capital’ on the job. It comprises of everything from career experiences, skills, learning etc.
We build this human capital and then spend it for getting our next role or job. This implies we must be aware of what we have earned, how much already earned, its sufficiency and how much to spend and where to spend. Essentially a ‘money’ framework to help us evaluate our career decisions and choices.
