I think another reason I'm hard on myself is I haven't really found what I like yet. So while I'm experimenting its not that I made crap it just tastes like it.
I think thats where vender juices come in at least for me it did. I found a few vender juices I liked then set my sights at making somthing similure. It don't have to be exact but similure. Once you find it you can experiment to get it as close as you can. I have not even come close to cloning a vender juice but got results I really like and in some cases even liked better then the vender juice.
