Well, if one is wishy-washy then that's one's problem. Typically once I make a choice, and I do mean choices that actually matter in my life, I don't look back from that moment forward.
Though, that said, IF I choose a path that doesn't pan out and one of the original alternative choices is still available then I reevaluate and make another choice. Otherwise I just move forward. One of the absolutely great things about time is that we cannot control the past; frees up a lot of mental energy.
And, on the subject of "make us more happy": Happiness is a choice, which usually requires and attitude adjustment on one's part and is NOT something that can be "attained" from any source outside ourselves.
I'm sorry, what does vrbo have to do with it, oh, that was an ad. Apologies.
Getting back to your point with the link: So a simple fact of life is that having "it all" is technically impossible as it implies that you can have things that are completely opposite, like having and not having your morning coffee.
And then also, not everyone wants "it all" because we all want something different.
Sorry again, but love, like most emotional responses, is not a choice. It either exists or doesn't.
Apologies for the short response, as I'd love to argue this further, but my employer "actually" expects me to be present at the workplace, and I'm already late.
