It’s never too late to be who you might have been.
George Eliot, English novelist (1819 - 1880) (from http://www.quotationspage.com/quote/31649.html)
In an interview, actor Meg Tilly said that her sister Jennifer (also an actor) gave her a gift that used that quote. Tilly had quit acting to focus on her family. Now she is back. No, it’s never too late.
