I don't resteem much. In fact, probably not enough to be a top notch Steemian. A while back, @son-of-satire posted a quiz as to what kind of Steemian we are https://steemit.com/game/@son-of-satire/what-type-of-steemian-are-you-original-interactive-quizgame which was fun.
Anyway resteeming... it's often a question of what I want my feed to look like. Which means I am pretty discerning with resteems... and I always try to space them out several hours from when I put up one of my own posts. And I pretty much avoid having more than four items a day (my posts + resteems) in my feed.
But that's just me.
Newish and new types couldn't go wrong by following this advice. If I could resteem a reply - I would lol. This would be a worth it one!
