Once in a lifetime

It’s funny to talk with my friends and family about my trips. They usually say something like this: now that you are in [any city or country I’ve been], you should go to [amazing place] It’s once in a lifetime man.
At the beginning I sort of believed it, but it can’t be some many once in a lifetime opportunities all the time, can it?
There isn’t such a thing as once in a lifetime thing. It’s all a state of mind.
Either we talk about trips, relationships or businesses, you decide how many once in a lifetime opportunities you get on a regular basis.
PS Even though there’ll be several in a lifetime, I choose to grab those opportunities. You know, just in case.
