So Bad at Gen Skill Checks

To preface this is probably such a stupid question and the answer is likely “just get better”.

I’ve just started playing the game and I’m desperate to get in the middle of things and help my teammates but I SUCK at skill checks. Does it piss everyone off when I’m trying to help someone on a gen and fuck up 2 out of 5 skill checks? Am i better off finding my own gen to blow up and alert the killer so people who are actually good at skill checks can do their thing? If I’ve understood correctly they repair faster with multiple people there but it feels like me screwing up skills checks makes it take the same amount of time as if i had left them alone anyways.

Also while i’m here what are the best perks for a new player? I main Ace with Dark Sense, Deja Vu, Self Care, and Bond.
