It could be a career, or religion. For me I was planning to become a pastor, but then became an atheist. It really did throw me off. In my case I think I’m much happier than I would have been, but do kick myself because I could have been positioned much better if I wasn’t making plans in this other direction.
I like and use signal, but of course the problem is convincing someone else to start using it in order to send you a message.
