I agree. Many students graduate and expect to be able to "follow their dreams". They are not flexible in taking jobs that are available. Many want to start at the top and are mystified when the seas will not part for them.
They need to bring their dream to the job avaiable not wait until their dream job is laid at their feet.
I've always been guided by chose a field you want to work in and you will probably never “work” a day in your life. If that field is working with your hands or if you are mechanically inclined, try a trade: A/C; Carpentry, Plumbing etc. If you see a future in another area, assess the opportunities at the other end of your path before starting.
In my case I loved photography (circa 1960). A mentor told me it was a difficult field. I considered Rochester Institute as I figured there would be a job at Kodak at the end. Fortunately for me, I could not afford it so I got a starter job at a bank and began an entry job in tada: Electronic Data Processing. I found I did not like it. Local College for Accounting, Army as a CI Agent, loved the work, and 35 years later left the investigative field feeling like I never worked a day in my life.
I recommend having a good mentor, a practical outlook, and experience (like a job or the military) to get a feel for what you will end up doing. Unfortunately, most “guidance” counselors today and part time parents, don't have the experiences or skills to guide anyone except into the “get a degree” choice.
