Journalling

I like to journal about my day, rambling or saying things that i figuredI thought about, that iI liked or more, (or something else / and other stuff).

"I" is always capitalized
I gave two options at the end more natural than "or more"

Also, iI like to write more infosgo into detail about my hobbies in my journal.

To "write more information" can be described as "going into detail." Details are extra information as opposed to essential/basic information

I like to journal about my day, r. Rambling or sayingabout the things that i figured,thought, the things that i liked or, and more.

Also, i like to write more infosrmation about my hobbies in my journal.

You could also say "things". We don't typically say "infos"
