The illusion of ownership

If we want (I certainly do) to get all philosophical here: There is no "your own [anything]" besides yourself, and even that is sometimes uncontrollable, thus not yours entirely

e.g. Let's say you go into a room with a coffee mug, whose coffee mug is it? You can have any instrument to measure the attribute called ownership. Fingerprints won't do because they don't prove the ownership, they prove only that someone has touched the mug. Ownership is a matter of belief (convincing others of it) and control (dominance over it: the one who can take it and keep it, has it.)

But in reality ownership is an illusion. Very useful illusion, without it we would be cave people, but still it is an illusion none the less. The mug has no quality called "ownership" , that quality is a construction in the mind of the people perceiving the mug if convinced of it, without convincing the default value usually is "not mine" and the connection between the "owner" and the object is imperceivable. There is no change in the properties of the mug, no matter who owns it, and the mug will not resist or behave any differently if someone else picks it up and leaves with it.

tl;dr: you don't own anything, but it is a VERY useful belief to think that you do (thought it has a price eventually: we run out of things to own, and the reality prevails causing us to revert back fighting to own "someone else's" stuff. Dreams and delusions have a cost.)

PS. Believing in stuff that doesn't exist and trying to manifest it in reality is like lighting a campfire, you'll need to constantly feed it to keep it alive. Either you give up the delusion at some point or you'll burn everything around it and then it dies regardless: the fire can't burn without a sacrifice, delusions have a price. Ground yourself in reality.

PPS. To offer a solution to everything:

1. Be really truly absolutely honest with yourself
2. Do only what you must (having fun and enjoying life is a must, just don't unnecessarily overdo it, it has a price)
3. Take/own only what you truly need, no more, no less. Since you have only what you truly need, you really can defend it like your life depended on it, if you happen to die, well then that's the reality: you were weak and no longer needed in this reality. If that doesn't suit you, make yourself stronger.
4. Make your life worth living and protect it the same way
5. Ignore the previous points if they didn't resonate with you: do your own thing.

Anyways, I'm gonna go make me some breakfast.
Toodles!
