This is something that is too obvious to us, right?
Of course the world isn’t fair. Some people are born rich, and some people are born poor. Some people get bullied for no reason, some people bully others. It’s irrational, and people don’t want to accept it, so they fight against it. But only the people that don’t give up are the ones that become the type of person they wish for.
The key is, you shouldn’t give up what you were fighting for unless you are wrong. You have to sacrifice a lot. Sometimes, you’ll be weary but its normal and that doesn’t mean that you should stop. You have to strive hard enough to achieve your goals and you must not stop till you reach the top.
