I think, first of all, that it is extremely important to let other people be. Forcing opinions, ideas, facts, thoughts, etc., just makes you a petty tyrant. Wanting to force your ideas, or what you know, down the throats of others is some obvious cancel culture know-it-all unnecessary strife-causing BS.
First, I grew up having psi experiences of many kinds, and was beaten, starved, and even had an exorcism done on me for telling them future events that came true. So I KNOW what I know, and nothing they do or say will upset that or take it away from me. I have taken the time to make sure I'm not insane, and proven the things I do with third parties or other veridical evidence. So I don't care about skeptics or non-believers, they can say, do, believe whatever they want and it doesn't change my worldview or the facts. It just shows they have closed minds and are the average narrow human.
My experiences got me looking at the occult, and trying a few things, but I determined that most of that was specific to the people who developed the practices, and those who are like them, or cut out of the same cloth.
The majority of occult systems are then other people's beliefs to me, since I don't need or require it, and it adds nothing of value to me or my life, or what I can do. It will never work for me, just like religions don't work for me.
So, my inner security and confidence comes from being capable of many supernatural things, and like I said, I then don't care what the doubting skeptic crowd thinks about it, and I have no need for their approval. I am also past demonstrations or questions. Fuck the public.
Any insecurities and lack of confidence comes from weak practices and beliefs that have no veridical evidence and no solid proof that you could present to these third parties or skeptics. If the practices or beliefs were solid enough, even I might be supportive of them, but I only support people finding what they resonate with, because when they do that, all of it works and they have results that give them confidence. If you aren't there yet, you likely haven't found your flock.
If you find yourself falling into the doubter, skeptic, zealot pile and thinking you need to feed it or defend your practices and beliefs, you need a new bunch of people to hang with.
