An interesting question was rhetorically posed to me the other day: Is there anything that simply isn't worth it? I immediately answered yes. My friend looked at me, smiled and said, "What?" And so I thought, again such a dangerous activity to provoke...it all depends on one's personal definition of worth. Is it furtherment in one's life, either socially, emotionally, physically or monetarily? Is it improving the standing of an object or individual? Is it both? Neither?
If I count worth as experience, then yes there is very little that just "isn't worth it," when experience is defined as gaining a better understanding of oneself and the world surrounding them. Every interaction, be it for the better or for the worse, has the ability to teach us something about ourselves, our actions, our interpretations, the way we love, etc. So just about anything we do can fall into the category of being "worth it" because, as hindsight increases, the full implications of that action/interaction becomes more clear.
But what if worth isn't just experience, but experience with purpose, like committing to something knowing full well what the consequences or outcomes are going to be? If that idea holds true then mistakes can never garner enough value to ever warrant being considered worth it; a flub and the consequences of it are totally random and thus whatever worth they may have was just a random byproduct. In that case, hardly anything is worth it.
Regardless, I'm still milling my way through this idea: what in my life was simply not worth it? If by denouncing the worth of whatever experiences fall into that category, am I condemning myself by not being content with where I am currently? Obviously those experiences had some sort of influence on me; am I rejecting that impact? Ugh this makes my head hurt. Going to go play outside, and live to not regret it later.
