I understand what you are trying to say, just like having money in your pocket and forget you have money in your pocket and one day when you wear the cloth and you just dip and inside your pocket and you see some cash you forget in your pocket 
It is possible if you buy your Bitcoin at once and hold it but is not possible when you are buying your Bitcoin every week or month in a small quality.
The only thing I will say is that every Bitcoin investor should have patient see Bitcoin investment as a long term goal so it can help you remove your mind form it.
Me I'm a patient person I don't get moved when I have decided to save I'm using Bitcoin as my savings all the money I get I save it in Bitcoin.
I'm happy I'm investing or saving my money on something that can change my life for good in the future I so much trust Bitcoin

I so much trust Bitcoin It's basically just a term used for saying that you should buy and just don't think too much about it. It's obviously not possible for someone to invest money into something and then literally forget about it, you will surely think about it even if you don't want to, but what you said is what one needs; it's patience that can keep you from the temptations of the market if you have bought and had decided to keep them for a long term, but then when you see a certain price, you feel like you should sell them now thinking the market might drop from here and you will lose whatever profits you've gained so far.
That being said, in my opinion, there is nothing wrong with taking profits from time to time if you know you are going to save the money and then buy back when the market goes down. For example, if you have bought your Bitcoin at $30k, and then you sell some at $120k, you have already made a good profit, but then you wait for the market to dip again, or maybe wait for the bear market, and then you buy again, and keep holding again.
A lot of people use this strategy, and they make good profit overall, apart from what they are going to get in the long run.
