How can you be a brave person after going thru a lot ? how can you quit being lazy ? and how can you read more often ? also get better in math ?

Being "brave" is a quality that a lot of people define through different things. What one person might consider a brave action, another person might not. Now people go through a lot. That's just life. Some people go through enough to permanently scar them for life, but they do something about it. Others look to blame everything else around them. Family, life, having depression, not getting the pills they need, etc.

There's a lot of ways one might be considered brave. Staying strong through whatever it is you're going through is one way of being brave. Helping others is also a good way. It's acceptable to feel sorry for yourself, that's fine. That's only human. But when you keep doing that, and you let yourself slip, that's not fine. So, the question is: what do you consider being brave means?

Now, on the laziness factor of this question: In all honesty, being lazy isn't exactly acceptable in life. You want something, you have to work for it. That's just how life works. Being lazy is just an excuse to put off doing something else. Which means, most likely, somebody else has to clean up whatever your laziness is putting off. Usually the "somebody else" are the people close to you. And eventually, they'll just get sick of having to do everything for you. 

If you want to quit being lazy, then simply stop. There isn't any sort of magic word, or program you need to take. Just simply stop. It's cool to binge watch your favorite netflix shows and eat ice cream all night, but that's what's considered a reward after putting in hard work and getting done whatever needs to be done. 

On the reading topic: A lot of people say that they don't have time for things. Usually, in the case of adults, they LITERALLY don't have time to even go to the bathroom. For teens, and young adults, that's usually not the case. If you want to read more, the first thing you need to do is fine something that seriously interests you.

As a guy who loves reading, and has always loved reading, I can tell you this: Usually, the people who love reading grew up reading at an early age. Usually, the first type of book you ever pick up (willingly) is what gives you the motivation to read later on. You can't be 5 years old and pick up an auto-biography of Einstein and actually be expected to enjoy it. However, if your five years old, and you pick up a nice book about some crazy adventure, you'll be immediately engaged. 

So, if you want to read more, put off things that aren't important. Such as watching TV for 8+ hours, staying on your phone for 24+ hours, playing video games, whatever. Really, sitting down with a good book can be wonderful. Personally, I hate nonfiction. I read only fiction, and the day I ever like a nonfiction book will be the day the apocalypse will come.

If you'd like recommendations on good books, check out series such as:
39 Clues
Percy Jackson and the Olympians (I promise they're 100 times better than the movies)
The Hero's of Olympus
The Kane Chronicles
The Golden Door, The Silver Door, and the Wooden Door by Emily Rodda (continuation of the "Deltora Quest" series, also very good)
Pretty much any book written by Cassandra Clare
The Chronicles of Nick (Continuation of 30+ "Dark Hunter" novels, and a couple other books, though not required to have been read)

Now, on the "get better in math" topic. Really, some people just have a knack for certain subjects. If your failing in math, that's a pretty good hint your not very good at math. Now, why is that? Usually, if it's not just because of a deep hatred for math, it's because of your mindset. 

By that, I mean if you're the type of person who doesn't like anything that involves an overly excessive amount of work, if you don't take interest in the type of things that people would label you a "nerd" for, if you're the type of person who puts everything off, especially the stuff that you feel is too complicated and should never have existed, then naturally, you wouldn't like math.

Now, as for getting better at it, it just comes down to coming out of that bubble you live in, and taking interest in it. When you get math homework, don't automatically thing "GOD, STRIKE ME DOWN NOW!", Instead, try look at it and apply what you know towards it. If you DON'T know, it's most likely not because you haven't learned it, it's more likely you don't know it because you just didn't care when you were being taught it, and you were thinking about what's for lunch, what your friends are doing, being anywhere else, etc.

Well, that's my advice on life and etc
Hope that helps you out.
