One adult decision you could ever make is to accept that there is nothing you can do about the past.
You can’t go back and make more time where you have squandered it; you can’t un-date that man that broke your heart; you can’t make debt disappear; you can’t take back what you said and no, you can’t give your children back 🙂
When that time has past, there is absolutely nothing you can do about it.
However, the future or even tomorrow or the very next minute you take a breath – that’s something you can change. Let’s stop spending an inordinate amount of time regretting not doing this or having that. Tomorrow, if not that next minute, offers a fresh opportunity to start from where you are and leave the past in the past. By all means, learn from the past but for heaven’s sake, leave it there.
And then you are left with another adult decision – to accept that only you can change what you don’t like.
