Every choice we make

Everyone makes a youthful promise not to get old and regretful, but every choice we make, by definition, rules out something else, so there’s always something to what-if about. Even the people happiest to be doing X are still going to wonder occasionally, what if they’d chosen Y? Sometimes this is sad, yes. Sometimes, though, it’s just routine maintenance on an open and dynamic mind.
