I can’t really answer for just one thing, but the most recent thing is that I wish I had treated a few people better at my job. Including my two work besties. They both left the same year and I got quite sad and depressed about it and a year later I got the sack/fired from my job. Four years later and I see them both again separately and they’re on my social media now but it’s not the same.
@swirlie Coworker got depression and thought I was talking about her. She wasn’t there a lot during that time and people started to talk about her at work. She overheard another friend of mine at work say something about her to someone else but I wasn’t there at the time. She didn’t like that me and this other coworker in question were becoming friends and she told my manager before she walked out that she didn’t want to hear from me again.
I wouldn't do anything different. One decision led to the next which led me to where I am today. If I went back and changed even ONE decision I'd made and did the opposite, I would not end up where I am today because a different path would have resulted. Life is good!
Either not go into the military or had written guarantees in that military contract. The former would likely be the case, since the military wouldn't likely put guarantees in most contracts.
