Realist vs Pessimist

There's this famous question, "Is your glass half-filled or half-empty?"

I have no idea if there's a right answer, but most people say being optimistic is the right mindset to go. And on some circumstances, I am optimistic.

There goes my mantra, "Things will get better."

So, am I?

I don't think so. Not anymore. If I dig a little deeper, I'll realize I am neither an optimist nor a pessimist. I am a realist. And it might seem pessimism at first but it's not. Let me expand further.

Half-filled. Things will get better. Because time doesn't stop to deal with my petty problems. No matter how bad of luck occurs in one day, it will pass. Tomorrow will always be there. And the greatest thing about tomorrow is that there is no mistake in it yet (Tumblr credit right there). That's optimism, right? Because reality states that life goes on, with or without you in it. So what's the point? Deal with it. Suck it up and move on. It will get better. 

Half-empty. Shit happens. Because life happens. Sometimes you lose, you stumble, and so what? It's reality. Is that pessimism? If I join some project and expect that it might flop, is that pessimism? Or am I just preparing myself for reality? If I look at a person and see his flaws first is that pessimism? Don't I only expect him to be a better person? Figure out what's missing and work with it? Strive to be better? Because the first step is always to identify the problem first. So is that pessimism? Identifying the problem? Seeing the problem? Before one can solve it?

Is my standard too high? No, I just know life. And life is a game. And to win a game you need to learn the rules first.
