"It's never too late to be what you might have become!"
Sometimes it's better if we aren't what we might have become.
And, yes, it can be too late, depending on what your goal is. Sorry for the injection of realism (or pessimism, as my wife calls it).
Now to work! I know I'm 54 and can't swim very well, but the Summer Olympics are approaching, and it's never too late! Right?????
