Have a routine that you use to start your day that becomes automatic and thoughtless. It's really hard to write a 80,000-word novel, but it's very simple to write down 500 words every morning if it's so embedded into your routine that you don't even have to think about it (and at that rate your novel will be complete in just over five months).
I was so consumed in myself and my needs that no one or nothing else was as important. I am disappointed that I hurt those that had given me nothing but love, compassion and fifth chances.

I hope it's okay to go a bit older than people in their 40s and 50s. I'm a family sociologist at Cornell, and we surveyed over 1200 people over 60 on this very topic (described in the book 30 Lessons for Living: Tried and True Advice from the Wisest Americans).
