25M working in sales, been through lots of ups and downs in the past few years

I've been trying to digest the pill for over a year now, and some of it has proved really effective, but I still have a huge hole in a lot of aspects of my life. Mostly that I haven't exactly solidified my mission, or worked out exactly in which direction I want my life to go. People say it can take a while, but I know that you also just have to try things until something clicks.

So that's what I'm wondering - when was your lightbulb moment, when it all kind of fell together and your life took off? Or was it just a gradual process? This could refer to girls, career, money, whatever.
