People plays different role in life depends on the stages they're in. They enter one stage at a time explore and develop themselves to become a grown person. As they grow the problems became harder and stronger as well for you to improve as an individual.
There are times that when you're still a kid your parents always lecture you about everything, prepare you for the battle in life that you will facing when you get old. Kids always enjoy small things because they didn't know a lot in this world. As they've start to learn they will become woke about the real happenings in our world. These learnings make you who you are, but it also creates problems that you're not yet facing. You will start to struggle and begin to think that the wonderful and beautiful life you have when you're still a kid is really horrible and miserable because of problems. Some people think this way, some treats problems as one of the rooms for improvement.
Life really is a mysterious thing you have your own meaning depends on the experiences you have. You must enjoy your life as a kid. When your only problem is to sleep during afternoon, or how to win while playing games, or how to memorize our national anthem. Treasure everything that you have. Enjoy your childhood, stop wishing to grow faster because you will regret that you didn't enjoy your childhood and youth when time goes by. Became an adult or grown man is not that fun at all, you will face a bunch of horrible things and problems so enjoy your life because you only live once. We can't turn back the time that we missed.
Best thing about being a child is you have nothing to fear. You didn't think that much, you don't anticipate things. You'll not think what might happen tomorrow because you enjoy everything that's happening now. And also the genuine happiness tha every child has.
