My dad was forcibly retired from his job as a chemist. I suggested that since he has multiple degrees in science, he should try teaching at college. But apparently he has his mind set on building a breakfast/lunch restaurant on the Jersey shore. I'd have never pegged him for that type of guy. Apparently the food service business is quite a draw for old guys.

Food service isn't a business to take lightly. I've known and worked for people in the same position, and it's a constant struggle. Having started my own business (in software, which I'd think is slightly easier to get off the ground), I can tell you that it's one of the worst experiences you can go through in life. (One that I would recommend without hesitation.) Unless your dad is already well off, I can almost guarantee he'll be broke and in debt at the end of year one. His personal life, long-term plans and well-being will suffer. Hard work pays off though-- and if he can somehow survive that ordeal, he'll come out the other end with a newfound appreciation for his ability as well as a profitable venture. Ultimately, it all hinges on his confidence and desire to succeed. And if he minds coming home smelling like pickles.
