This is what I realized; no matter how much you love your work/profession when you started out, it's impossible to keep that flame of curiosity and interest after 15-20 years of work. You need to get away from it frequently to rekindle that flame. Find hobbies that have nothing to do with technology or computers or programming like playing instruments, hiking, running, knitting or whatever else that interests you.
