An example of keeping things simple is that instead of storing your Bitcoin in a multi signature wallet that you do not understand how it works or have no experience in setting up, store your Bitcoin in a soft like Electrum wallet where the process of setting up is pretty straight forward.
Storing your Bitcoin in multi signature wallet is actually not too complicated. I think if you don't have the ability to assimilate simple things like this then I fear in general for the person's safety in crypto-currency. But out of preference and not complexity I use electrum because it has been what I started with and it's work fine for me.
I believe it's all about individual preferences, how I would choose to save my seed phrase may be different from how you would choose to save your and so is the same with how I choose to save my Bitcoin. But this factors should not be overlooked and that's it must be safe, easy for you to access and private to other people.
