I think if you are making a complete career change it has to be something you love. This just me and the entrepreneur in me . Why just go get stuck in the same thing ?... "a job" .
What I would do is this ...
I would just look at what I enjoy doing ... ( when it comes to working and career )
If it is coding or marketing or whatever.
How can I turn this into a business ?
What are you good at ? Can you teach it ?
Do you even like teaching ?
Can you freelance what your good at ?
Do you need professional training at what you enjoy doing ?
Is the codesmith etc. bootcamp something you would enjoy ?
Here is a big question ... How long can you go without an income ?
Just my opinion... at 37 the only change I would make would be starting my own business .
