quit. I've been through 4 jobs within a year in a half and finally found the job that fits and gives me the challenge and freedoms I want. the beauty about today is we have an opportunity to decide where we go because the demand is ridiculously high. You as a developer, should always strive for a challenge, whether that's at the job or at home doing a personal project, but always strive for happiness in what you do.
I guess me trying to keep up on other languages is sort of a way for me to know that I'll still be valuable in the market later on, if the time comes.(hopefully)
