Well, as a beginner at bitcointalkz, or for you who just started new, you've gotta try as much as (basically everyday) to keep sharing contents or making eligible posts with also commenting on other people's contents in order to grow your status. When you share your contents here and it is very valid and formidable, people begin to ask questions that could lead to them commending your efforts or contents, by so doing you earn merits from encouraging people.
It isn't a must to keep on sharing content everyday as you say, this isn't some social media platforms were you have to constantly engage your followers or audience to stay relevant. What matters must here is the content that they're sharing, hope it's informative, educative or adding to the growth of the forum in generally. Those are what make you get rewarded and not not when you're staying active in hope of getting rewarded with merit, you won't get it. You could as well only write when you see something worth contributing to and still have enough merits to rank up due to the quality of your works then someone who's active everybody just been active without any impact.
As for consistency been the way to excellence, that's quite true but not when you're doing the wrong thing consistently. For example, spamming or writing generically doesn't contributions to your growth on the forum instead it labels you with been a nuisance to the forum which will probably ends you in meriters blacklist and also reduce your chances of getting hire inrto campaigns etc. If you're been consistent, make sure you're doing such with the right things like instead of been consistent with your writing on the forum, you could do more of reading and watch how impactful that'll be to your life.
