Even if you're having a bad day, you can rest guaranteed that it won't last forever. "This too shall pass" is a phrase you may have heard, but it pays to start believing it.
Even though it would be great if everything were fair, it just isn't. There are good times and bad times in life, and some people are dealt better hands than others.
On your best and worst days, your family will be there for you. If you're lucky, you might have friends who are just as good as family, but most of the time, your family will be there for you.
If someone seems angry, they are probably afraid. If you're angry, it could be because you're afraid of failing, you're upset, you don't feel safe, etc.
You'll be safe if you don't take any risks, but you won't be happy. If you don't learn to take risks, you might not meet all of your goals.
This isn't meant to be a bad thing; it's a good thing. Most likely, the world and the people around you don't judge you as much as you think they do.
They choose happiness! Nothing will happen to you that will make you happy, so go out and make the life you want.
