planning to trip for the first time soon

I just ordered a gram of 10x extract as well as about an ounce of leaves. I have smoked weed for a little over a year and have had some drinks occasionally at social gatherings, havent tried any psychedelics yet, this will be my first time. I plan to use a bong and have my father (who has tripped before) tripsit me in a familiar environment without excessive stimuli. I really want to be responsible about this and do my best to give myself a good trip. I have read that even 10x extract is often too much for a first time, so I am gonna start off with the leaves. My next question is, is there a “right amount” to use? Any advice is welcome. I am a huge pothead and love my weed, but I am interested in a new experience. I am aware it is nothing like weed, but it is an experience I am curious to have. If there’s anything you think I should know, let me hear it, thanks! :)
