What will happen if people can reach their full potential? (Personal Essay)

They say the world could be a better place, but no one knows how. I mean, how can we know, right? We don’t even know how to make ourselves better in the first place.
But of course, I’m only speaking for myself. I might not know how to make myself better, but others may have discovered how. I get envious whenever I think of that.
I wish I know how to make myself better and then maybe I could be a part of the thriving percentage of people who try make the world a better place. The people who have a hold of their own happiness. People who are able to showcase their hundred percent.
And with this thought, I sometimes think what would happen if people were able reach their full potential? What would happen if their status in life doesn’t affect their dreams or their talents? What if there’s no limitation or restriction to what they can and wanted to do? Would it make a significant difference? Would it make the world a better place?
And what is a better place, anyway? I don’t exactly know how to describe it but it has to be a place where you could see a rainbow wherever you look. A place where you don’t have to shout in order to be heard, you just have to smile and every one will already see the light within you.
There’s a light in everybody, I believe. But often it was overshadowed by insecurities and fears. By the persisting evil thought that tells you that you CAN’T do the thing.
Well, of course you can. You can, but most of the time, you tend to focus on the distasteful reality. This distasteful reality that makes you feel helpless but never numb.
What’s that? A feeling where you don’t have the strength to act, yet you’re sensible enough to know that you have to. It’s like standing in front of a locked door in weak knees, glaring at the key trapped inside your own tight grip.

For what it’s worth, you’re paid to hold that key but never to open the door. The door that would allow you go even beyond your hundred percent. You can actually risk it, however, you’re afraid to lose the remuneration that neither confirm nor deny your future.
It’s the second saddest part, I think. The uncertainty the comes in the future—and present—while you press the key inside your hand as you try to take a peek behind the door. You don’t know whether you’ll be able to be a better person. You don’t even know whether you could still experience a better world. Or at least be a part of it.
I don’t think I can see rainbows everywhere in the near future. And I don’t think I’ll be heard through my smile. But one thing’s certain, I wanted to be a better person.
