I have never gotten a good high. What am I doing wrong?

I really love the concept of trees but every time I talk to someone who's at a 5+ or read posts on r/trees, I realize I've never been that high. Maybe a rare [4] once, and I've been smoking since October. I have an MFLB, a small gravity bong, and a good glass pipe. I've also got a small amount of ABV sitting around but not too sure about going into edibles yet.

The MFLB tends to keep me around a [3] for hours and hours with how I use it, the gravity bong floors me too quickly and makes me scared to go any higher, and the pipe is nice but a bit harsh. By the time I get to a second bowl I usually feel a bit lethargic and sick and don't feel like smoking anymore.

Tonight I want to hit a [6] or [7]. I feel like smoking this long would rule out the amateur mistakes, I hope I haven't gone through this much without inhaling properly or something. I know the obvious solution is "smoke more" but I'm definitely using way too much at this point for too little.

My only guess is that my hits aren't "dense" enough. I get a good amount, inhale deeply for awhile, and then get a sharp inhale with the last of my breath, but it feels like it isn't pushing very far down, nor does it exhale through my nose if I feel like "checking." Would hitting harder in a short time and leaving room for a huge breath of air work? I'm not really good with the larger hits.

Any input is appreciated. I want to see what its like.
