do you mean rapid and sustainable growth of your account? the only way that could happen is if you are consistently providing/sharing good information, contribute to the discussion or the forum. but don't always expect to be rewarded for everything that you do or you think that you did good.

if you want some inspiration I suggest looking at the thread created by LoyceV The future of Bitcointalk: Low Ranking Top Merit earners in the past 30 days. the thread consists of newbies or former newbies, some of those that are on the lists have already reached legendary rank. Good luck with your journey here in the forum.
