"Don't expect to build up the weak by pulling down the strong."
There are lots of ways to build people up and encourage them. Some of them are wrong while others are more kosher.
By pulling others down in the pits, whether they be strong or weak, it does the opposite of any good-intention goal.
I will forever stress how important writting communities are. Most likely you will hear from other writers as well. These wonderful people are there to lift you up when you're feeling down in the pits. They have been there, right where you are now, and they are specifically there to build you up in your writing journey through all the right morally based reasons. Sure it maybe awkward at first, but think of it as a cult or a super cool club in school you were never invited to join. The main point is we are all joined but a mutual common interest and we can only build each other up by joining together and rising together.
