Dude, I was an Emerg doc. I just finished the 5 year diagnostic radiology residency and I am starting an interventional radiology fellowship. I am married with small kids.
Don't go back to school for 5 years. The price you pay with respect to not seeing your kids grow is too high.
Follow the self-study route. You can always hire technical people to assist you.
Here is another perspective: If you live a comfortable life and have a beautiful family, why not enjoy them?
Well, I do enjoy my family and friends, but they are also busy and have their own lives (school, work, etc). I'm not willing to be an absent father, but in reality I have 3 full open days in my week and I'm bored to tears. Should I just fill up my time with more work, just to buy more stuff than we need, or maybe engaging in some mildly satisfying hobby?
PG discusses this in one of his essays, when he points out that happiness must be considered in different time frames (one hour, one day, one week, one month, etc). Besides that, I really feel the urge to create things.
