When I'm not motivated as much by anything, be it relationships, money, hunger, power, pleasure etc. I have to inspire myself instead by removing anything that makes action undesirable, such as anxiety and fear. And to remove anxiety and fear I have to remind myself that nothing matters and that I'm going to eventually die, which is a kind of motivation I've been trying to use for a few years. It is sort of helpful for me to think of death and how temporary I am just so I can feel like I can do something without it affecting me badly..... everything neutralizes itself, so what does it matter that I did that one thing? And yes it also helps with indecisiveness, I need a lil kick instead of wondering about what could happen.
But ye if I weren't at least a little chaotic and reckless in what I did, I'd probably be depressed/apathetic/indecisive as a result, and I don't want that. I want to not give a fuck. I need to be that way for me to move forward if I can't just do it purely for a future goal or reward. I have to do what makes me happy in the moment.
Other people may romanticize death and suicide because people like to be attached to things that make their life meaningful. Death might be a sort of final goal for them, something to be attracted to so that they can feel accomplished with their life.
edit: and I'm a pretty positive person I think, I like to see the best in everything, which is exactly why I'm the kind of person who can benefit from seeing death in the distance, it's a neutral thing to me and I can be inspired from it
