I think I need to brush up on my social skills now.
Nono, hold them where they are, they are good this way. And leave the rest to the self preservation 7s, who are the most gluttonous of the 7s. they are ambitious, comfort seeking, usually somewhat ruthless and often fit the shrewd businessman archetype nicely.
That's more akin to avarice. Gluttony in the 7 is directed toward doing everything imaginable in the real world. Sp 7s hang back more and act more like 5s. Gluttony does not have a negative connotation here, it simply means wanting to do everything (in the case of the 7s). You are comparing it to miserly, which is closer to the 5s fixation and the 7s integration point.
Counter-Gluttony 7: Hang back, plan more long term, act more decisively, much more organized. Medium Energy
Regular 7: Participate, plan more short term, act more in-the-moment and a bit impulsively, fairly disorganized. High Energy.
I recommend reading R&H's description of Sp 7. they illustrate my point nicely.
