I use my "20 year" theory.

In 20 years, will it matter?  As most things become a distant memory.

I apply it to work, relationships, mishaps, positives, and so on.

For example, a friend was complaining about his cousin & his hairbrained schemes &, pie in the sky, talk.  It really bothered him to the point of destroying the relationship.

So, I said, add 20 years, he probably won't be around, and you'll miss him dearly.
Because, some of those, pies, have borne fruit, enterprise, other ideas, projects, & revenues.

Sometimes the investments you have are right in the palm of your hand.  They are more valuable than a portfolio of numbers & future consternation.
