Sometimes, we have to accept things we don't like. At school, we have no choice. And when we grow up, not everyone is lucky enough to land their dream job. We soon realise that we can't have everything we want. So, we need to be more mature, and accept that things won't always go our way.
When we were children, our parents would give us many things to make us happy. But, as we become older, we have to change our attitude.
For example, if we have to go to a school we don't like, we shouldn't complain. We should try to make the best out of the opportunity. Then only can we enjoy life and studies.
Some people quit their jobs simply because they don't like the work. But if they are mature enough, they should realise that they cannot have everything they want.
This society is not a wonderland; it's an interactive community. One decision can ruin lots of things. If people only want to do the things they like, it can be a bad influence on their lives.
So grow up and try to accept the rules of this world.
