This world needs ordinary people; without them, how could the concept of genius even exist?
This world needs homosexuals; without them, if there's an imbalance in gender populations, some people would inevitably be left without partners.
This world needs effort; without it, everything would be too easy and lose its fun.
This world needs people of different heights; if everyone were the same height, it would be too monotonous.
This world needs flaws; without them, we wouldn't be human.
But what about people with physical disabilities—does the world still need them? Of course, because the world needs them to manifest love.
So, you are important.
It is precisely because of flaws and limitations that there are things we can't obtain and things we can't do. That's why this world has so many magical, interesting, and admirable things—science, various technologies, great achievements, and those stories of people overcoming their innate limitations, improving their shortcomings, breaking free from the shackles of their upbringing, and refusing to bow to fate or reality. Of course, there's a dark side too, where the multifaceted nature of evil and sin emerges from this.
Being human, one of the interesting aspects is imperfection. The influence produced by imperfection guides our actions, and different people take different actions, which is exactly what creates the diverse faces of the world.
And my favorite action is: "We don’t quit, we don’t cower, we don’t run. We endure and conquer." - Kobe Bryant. Stories of continuous growth and constant discovery are what I think make life both fun and painful. The world always has treasures buried by God waiting for you to discover; the things we don't know outnumber the things we do by infinite multiples
