“I just

feel

like it’s time for me to get a different perspective on live. My motive is

not emotional

, it’s just logical.”
You contradict yourself here. If it is a feeling, where is the logic?
And I think it’s quite alright to contradict yourself, but better if you know you are doing it.
In my experience, logic itself is circumstantial. It is a tool of consistency that people use, but people can use it for different things. Something that I think about is that there is nothing that is not circumstantial (Non-independent origination, Heart Sutra).

Talking about your uncle:
“I asked if he was sad when his parents died and he said that he wasn’t sad, because everybody dies. He also said that when you see the world with total objectivity, you will be at peace even if there’s a war going on outside.”
It seems as though you are saying “I should be objective, so I can be at peace”. That itself is a desire. It’s one thing to tell the truth, that you are not sad, like your uncle did. It is another thing to want the truth, to want not to be sad. One is unmotivated. The other is motivated, moving in a direction; from here, towards there.
In my view, it is not a wrong thing: “to want”, to be motivated. But I think it is confusing to say that your motivator is logical, and without circumstance. Some psychologists say there is no such thing as motivation without affect (without emotion).
To finish: If circumstantial means “not real”, then nothing is real….Just like the Buddha always knew, that life is a dream.
