Before i started my bachelors degree program, i considered 5 or 6 different careers. I 'generated' this list by applying several 'filters'. "Guidance counselors" usually say that the only criteria is "you have to like what you do". This is the only filter that they apply. This is lousy advice. I like listening to rock music - so i'm going to make a living doing that!! RIIGHT!!
My 'filters' were: a> can i make a decent living doing this? [decent living being defined as being in the top 20% or so of wage earners], b> will the profession outlive me? [will i be able to get a job doing it, as long as i want one? I don't want to be a buggy whip maker when petrol autos come in, c> Am i so positioned that i can acquire the credentialisation necessary to do this job, and can i continue to do it for the rest of my working life? [being a champion mile runner, or olympic figure skating star, can only last for a few years. You won't see 50 yr olds doing it, but you'll still be alive (hopefully) at 50, and need income, IF you are a retired footie player, or coach [which is what players normally 'morph' into], can you find employment in something (other than sweeping the streets) at 50?, d> Am i reasonably protected from having my job "exported"? [is it something that could not reasonably be 'outsourced' to Hong Kong, mainland China, or elsewhere?] e> are there enough different 'facets' of this job, that over time, i can change to a different facet, if the market dries up for the one i am engaged in, without a lot of 're-training' being required?, f> jobs are 'created' by market conditions and new developments over time. Many new jobs don't exist when you start your degree program, but become 'big' later. Will my training and experience be broad enough that i can change over into one of these 'new' fields, without having to start my degree program over? g> lastly: Will i "like" doing this, (or something like it) for the rest of my life. This is probably 50 to 60 years.
I applied those filters, and interviewed at least 4 adults that were qualified (and practicing the profession) in each of those industries. I asked: "How much do you make", "Where do you see yourself in 5 yrs, 10 years", "What would you have done differently, if you had your education to do over"? "What other professions did you consider, when you were where i am now?"
My choice, after doing all of this, was electrical engineering [BSEE]1969. I later went back - after working 10 yrs or so, and upgraded my credentials to a master's degree [MSEE]1987. I think (in retrospect), that those were good decisions. Best of luck!!
