I'd recommend quitting entirely. You don't need it and it sounds like you can't help but have an unhealthy relationship with it. IMO like similar things, it's an amazing tool, medicine, and recreation, but it should be removed if it's getting in the way of your life.

I've gone through two weed periods in my life and while I did benefit from the perspective shift, during each period I began to suspect it was interfering with my goals. If you're not meeting your goals, you need to change things until you do meet them. Removing routine consumption of a powerful medicine that's known to affect motivation, attention, and memory (and differently for everyone which is why you can't trust anyone's "well, it works for me") seems like a natural thing to do.

Consider it an experiment and stop consuming it for 6 months while studying your progress on things that are important to you. For me, after about 8 weeks of ending my last "period," I began making progress on my goals in ways that I hadn't before. Weed made my thinking sloppy and I was stuck thinking rather than doing, exploring rather than exploiting.

Everyone that regularly consumes it thinks it's net-good for them (I certainly did). It's worth seriously considering that might not be the case for you and you cannot know until you take a long break and measure your experience.
