admirable. I'd suggest saving what you wrote to your e-diary, printing it or something. To look back upon and see how far you've come months and then years from now.
Those four years prepared ya for your next phase, building the person you are today, ready to face kal and parsoun. Isn't it great to have all those questions unanswered at this point in time, to have something to look forward to, something to push you, motivate you? Wouldn't be much of a ride if we knew all the answers before even going down that stretch of road.
You're only going to go from strength to strength from this point on. Welcome to the jungle, you'll be fine.
