I would agree not to worry too much about numbers. Almost everyone who competes loves the experience and it drives them to train harder.
That being said, when I think "respectable numbers," especially at a weight class like 181, I think multiples of bodyweight can be good goals to shoot for. I would say a 1.5 x bodyweight bench, 2 x bodyweight squat, and 2.5 x bodyweight dead would be very respectable at 181. So that's 365/275/455.
Again, maybe to you these numbers are WAY high or WAY low. The important thing is to compete if that's what you want, and not give a shit about what other people are doing. But if you are looking for some goals, I would say those numbers are a good place to start.
