I know how you feel and feel it too, I think many do.

Here's the thing though...I just wrote a post for later about the perfect enough paradigm. Nothing is ever going to be perfect, certainly not life itself, so it's best to find enjoyment and value in the perfect enough moments and things in our lives knowing that there's room for improvement. That way we enjoy our lives now with a forward-focus, meaning hope and momentum to carry us forward towards something better, more valuable or enjoyable. It's a mindset but one that leaves me happier [now] and with less chance for regret to creep in later.

There's a book for sure mate, we are all a tale waiting to be told.
