How am i supposed to put egoism into action exactly

How does an egoist behave, exactly.

Does he just disregard laws if he thinks he wont get caught or is there more to it?

If they have the Will to, indeed.

An egoist will break the law if it's in their interest to do so, but at the same time they understand consequences, so i don't think it's something they will do often unless its absolutely necessary.

Know what is best for you and have the will to do it.

"Can I get the metro without a ticket? Are the chances of me getting caught low enough? I will do it!"

Yeah, well.

Of course the person would have to want to get on the metro too, and want to cheat the system. Being an egoist doesn't mean just doing shit for the hell of it.

just act like kanye west

It's like a pedophile who rapes children.

...

If not paying ticket will benefit you, why pay ticket?

Because you understand that if you do not eventually there will be no trains or perhaps because it is not within your nature to cheat.
