In my 50s I looked at the walls around me -- marriage, work, lifestyle - and wondered if they were keeping my life together or keeping life out. I know people who seem perfectly content with their lives. That ain't me.
Passion, purpose and possibility after 50: does that describe what you're looking for? Well, your timing couldn't be better. Something big is just beginning that will help your quest; how we think about this stage of life is dramatically changing.
