As far as you know today, this is your one and only life. If you live to age ninety, figure out how many days left you have to live. Really, add it up. You have a limited number of days, so do you want to waste one of them feeling bad about yourself and not demanding the best life has to offer? Do you really want to let others determine how you will live, or give away your precious life to fear?
All of this is a choice for every one of us. It seems like a “no brainer” to change.
