I've always felt it's unfortunate that so many of the choices we make as young people (when we're least prepared to make profound life-changing decisions) can have such profound impacts on the rest of our lives. However, that's life: and it's never too late to make different choices to change your direction. It's obviously easier to build on successes and achievements in our lives than it is to overcome the mistakes we've made, but in most cases it's not impossible.
