though some RPs in advanced use such lengths, not all do. In the RP we're running there, we generally don't care how much someone writes in a post (within reason), but rather what they do with it. Also, Aftermath (our RP) uses collabs heavily, which naturally tends towards far longer posts.

Give it time, and you will learn to write more too, [@Rockerman403]. Especially if you find the right GM that doesn't mind having someone around who posts shorter than the rest do. 

[list][*][b]Tip #1: [/b]Find a GM that will let you participate even if you can't post the same lengths as all others can.
[*][b]Tip #2:[/b] Collabs with people who typically write longer. Though a 30-para collab can seem massive, remember that only half of that comes from each player, and that it is helped along by the other participant.
[*][b]Tip #3:[/b] Take your time. While some advanced RPs can have posts thrown in pretty quickly, most move at a slower pace than casual. Not all can throw up a long post in an hour. Some might write the post over several days, if not longer. Most reasonable GMs accept that posts may not come as quickly from all players.
[*][b]Tip #4:[/b] Have fun and make sure your character has sufficient depth. We've seen in the past how some characters sort of "overrule" their players in what they will/won't do. Those types of characters can easily let you churn out more than you otherwise would. [/list]

any questions?
