How far should one go to be frugal and stack?

I hope this is a fun post. I noticed a lot of people post about how they are skipping coffee, or wearing hand-me-downs, or driving a 27 year old car with no A/C, or eating ramen noodles to stack.

My question is how much is too far? For example, I am never going to sell my car and just take the bus. Would waste way too much time. I'm not even gonna downgrade my car - I like leather seats and some power. Not shopping at a thrift store for clothes. Good fitting clothes makes you look more respectable and presentable socially. I am also not going to sacrifice my health - so eating Costco hotdogs or noodles instead of eggs, steaks, etc is off the table. Coffee? I dont drink it but I seriously don't think the 3 or 4 dollars a day max is gonna make that much of dent. I'll also drop whatever it takes on gym equipment if I feel it is needed.

I guess for me it is important to live a normal daily healthy life while stacking. I don't eat out or go out that much. I dont have expensive habits. Definitely not opening up a bottle of wine every night or even every month. Not going to drop big money on a night out. No clubs, bottle service etc. Rather have Bitcoin.

What's your line/limit? What are you willing to sacrifice (or not) just to save?
