Even though this topic was brought back from the dead, I find it very interesting that you post this following your visa issuance, whereas if one looks at your post history before October 2012, they will not only find the positiveness you espouse, but find you complaining and expressing both doubt and negativity about the timeline/process.
You'd have a lot more validity in your post had you not been a hypocrite and doing what you are telling others not to do (those who do so for rather valid reasons, even if they are irrational sometimes), and if you had not decided to post this at the most convenient of times.. after you're finished.
I had virtually no problems during the process myself, and while I find some good in the message of staying positive, the gravity and uncertainty of the situation logically will make people uneasy. Rather than being up on a pedestal, try and actually put people's minds at ease by helping them with information instead of preaching from the pulpit like a hypocrite.
