The answer is simple; if you do NOT need the money from working as a SE in the Tech Industry, don't go in. You will burnout. It will affect your brain and health in ways whose consequences we do not yet fully understand because the effect is cumulative over time. Even if you don't dramatically break down one day, you will be worn down in ways which you may find hard to reconcile with your past self.

Now Tech itself is interesting and enticing. The problem is that the "Tech Development Industry" has made the environment around it poisonous. Everything is judged according to its monetary value, insane competitive pace and work schedule, no planned time for rest, recuperation and recharge, constantly shifting landscapes, herculean demands on your brain as regards coping with complexity and finally, quite complex human interaction dynamics. For some reason the industry completely ignores the psychological aspects involved though it has been studied from the beginning (see the works of Gerald Weinberg) and we now know more about the human brain and how it works. I have come to the conclusion that working in the tech industry is "death by a thousand cuts" where the cuts are in your psyche/brain draining the "joy of life" out slowly.

Very few people are able to come to some sort of understanding between their work and passion such that the downward decline is arrested and settle down to a comfortable plateau.
