NL 100 Zoom Players Pokerstars

Hey buddy, I used to play NL50 zoom on stars precovid but took years off because I wasn't educated enough and it was more borderline gambling at the time. About 6 months ago I got back into poker on GG with the goal of gradually becoming a positive player reliably and make consistent preogress with my bankroll. I was rusty and losing at first but have since climbed from NL2 with good bankroll management to NL25 as a consistent winner. Unfortunately I went against my management recently and am back at NL2. I have taken this time to study up as I go through the yawn, boring process of rebuilding. I joined this chat specifically because obviously NL2-10 players are not well versed in strategy. The main issue I am facing right now is that people open a lot wider at NL2 obviously with both limps and RFI's. I understand that when people overcall, your fold equity goes down and thus, you have to tighten up. Also when someone has already raised or limped, there is competition for the pot and you have to tighten up. I am having a hard time knowing where to draw the line because it feels like I hardly get to play following these principals. I have mainly been tightening up my RFI when there are limpers behind me and trying to get them to fold. With that being said, it is hard to tell how much I should tighten up when I am first to put money in the pot and there are high vpip players to act still. I try to play in a variable way dependant on if they are out of position compared to me. I guess this is just rambling but I do have something to inquire about. When someone min raises as their RFI and I want to call, I am not sure what to do at times. On one hand, I don't want to fold ok hands to go in, on the other hand, people behind me are getting great odds, on the other hand, I don't want to 3bet with med strength hands to collect the fold equity. Do you have any suggestions when facing a min raise pre?

Thanks and kudos

What BRM would you suggest to not get back to NL2? I just moved to NL5 and definitely want to stay there at least, NL2 is too absurd
