The whole point of helping is to help people understand, but you overcomplicate it all. I excel at the English language, and I've roleplayed without a doubt more than you, and I still have problem understanding what it is you just said.
If you want to help people get into the art of roleplaying, you need to be clear and simple when you write.
This would be my translation of what you just said:
Do not underestimate the value in taking your time making a roleplay post. It is better to take things slow and think things through, than to rush it and hope to produce as many posts as possible. If you rush things, it's likely it will come out worse than it should.
If you write in fluency (Without, or with little pause), risks are that you make things up as you go along. When you do this, it will always turn out that it sounded better in your head than it did on text. Think before you write, and put every part of your creative mind to use. It is important to remember that we aren't you, and we don't understand how you think. You need to explain it to us.
When creating a character, there's no harm in deviating from your source of inspiration. If you want to base a character on Naruto, don't make an exact replica of the character; You will improve yourself by daring to make changes. Don't get too excited if you get inspired by the latest anime you watched. Begin creating a character, but stop and think about how you should play this character. Think about what role it will have in the roleplay, what kind of world the roleplay is revolving around, and what you hope the character will accomplish.
Don't get blindsided by your own excitement. Remember that you're in it for the story and not solely the development of your character. What you do should always in one way or the other contribute to the story of the roleplay, and it's important that you don't forget that. You should also consider that just because an idea seem cool at the time, deviating from the plot might not be such a good idea and might ruin the development experience for the rest of the group.
In all simplicity; Think and plan before you post anything; Both about your posts, and the posts of those around you.
