I'm about to finish the second year of my Masters degree in Robotics Engineering, ending on a particularly difficult mathematics heavy course (which was my biggest fear and weakness going into the Master's program).
I had graduated in 2009 with a robotics engineering degree and found not a soul hiring due to the economic collapse. After years of building a software engineering career (which was hard in it's own right) I can't find anyone who will take me on for a robotics oriented software position; most require tons of experience I wasn't granted the option to earn and/or advanced degrees.
...So I bit the bullet two years ago and started my Master's at night after work. It's exhausting but I'm inching closer to an advanced degree and, hopefully, a job working on software directly controlling robots in some way.
Decade+ career switches are hard
