Regrets are apart of being human. We can imagine oh so many different paths to take other than the one we took. When my biz partner embezeled and drove our biz into the ground, to help me, ive explored the root of emotions with help of trusted friends and a few professionals. There can be many paths to move forward with. Hopefully you have some friends to give you different perspectives and support the path you take.
Have you ever forgotten anything you needed for work at home, then just decided to take leave of the whole day instead?
