Marooned on Weak-Tight Island

[Festus22]

Here's the story:

I achieved a milestone this weekend by passing the $2K profit mark since I began playing more seriously in July. 95% of my play is at Party $0.5/1. My problem (at least I think it's one) is that I must have some kind of phobia toward PF raising. I'll raise AA, KK, QQ, AKs and AKo pretty much every time but I almost always limp all other playable hands. Of course if it's folded to me in MP with AQs I'll open raise but if I'm UTG with that hand, I'll almost always limp. Same for JJ, AJs, KQs, etc. It's funny in that when I click the "call" button, I know I "should" be raising but for some reason, I don't anyway.

Now when it comes to post flop play, I'm usually a fold/bet/raise (probably in that order) player. I rarely call unless it's something like a non-nut draw or a call/fold-the-turn-unimproved situation. I'm probably the anti-calling station and I think that helps me a lot. But what has been pointed out as another weakness is my showdown winning percentage which is currently around 75%. Some have said that's way too high and I'm folding too many potential winning hands. I would probably agree with that also.

So I don't raise enough PF and fold too many hands post flop. Here's my dilema. Even with these "faults", I've developed a winning strategy for Party $0.5/1 by playing this way and obviously don't want to do anything to screw it up. At this pace, I may make maybe $5K/yr playing $0.5/1 which is a nice little supplemental income. Yet I continue to feel I'm playing "incorrectly" based on posts and responses to posts.

Should I make a conscious effort to fundamentally change? Anyone have any advice?
