For my 50th birthday this past week I decided that it would be a lark to Tweet the 12 Things I Wish I Knew at 25. Or rather, things that had I either known them (or, more accurately, followed them) would have made my life a lot easier, and saved me a lot of heartache. Some are bits of advice that wisdom figures have told me during my Jesuit training and that took years to sink in. Others are the result of some hard knocks. A few are insights from the great spiritual masters that I've adapted for my own life. (Here's a confession: I often imagine my older self meeting my younger self and saying some of these things--especially Number One.) It was also fun trying to boil them down into the requisite 140 characters for Twitter. In any event, maybe some of them will help a 25-year-old you know. Maybe one or two will help you! Here they are.
