the process of gradual or unconscious assimilation of ideas, knowledge
Merriam Webster definition, ” a usually effortless often unconscious assimilation”. I found this word in the text ‘How better photos can help you document, and shape, your neighborhood’ by Patrick Sission

so this sentence now means “All of my writing and blogging, i learned from my dad…”
