Probably the most pivotal one I can think of was my introduction into the industry I work in. Just an 18yr old who needed a job, got invited to check out a small CNC job shop by a family friend. Fell in love with the industry and explosively grew my knowledge and skills. I was at that job less than a year but still in the industry many years later.
Not sure what my life would've been like otherwise, I had goals that disappeared when I entered the industry. So maybe I would've reached those, or had more/different friends through schooling. Either way, this is where is am.
I'm rarely on here outside of work. That being said, I did delete it at one point because my mental health took a dip. Seeing upset constantly in the news and memes etc. Takes a toll on me eventually. I do curate my feed a decent amount but some communities have such a mix that I keep them
