Imagine you had a job, you could only loose if you'ld burn down the company building. Let's say you earn a solid $50k. Your work is moderatly exciting, nothing that would really need your attention. You could basically spent the majority of the day on facebook. You have the additional chance to become a civil servant one day and have your retirement secured. Nothing really big but totally safe. And your current job is one of the most wanted and therefore hardest to get for its security.
The job tho bores the shit out of you. You being a young guy want to accomplish something still and think that you are basically a brainless zombie 24/7 in that job. Plus that your qualification is a totally different one from what you are doing now.
The qualification you have is one of the most wanted in your country right now. You could basically find a job anywhere. But it would be less secure and since you are planning to start a family you are wondering if you really should quit your secure job. Your qualification would mean to work in a company on the free market, which could kick you out if business runs bad. So a normal job.
You have the undenied support of your gf which says: go for your dream. (but who is a bit crazy as well)
What do you do: safe job until death or unsafe dream ?
