Day of rest. Went to church. We had a lesson in the elders quorum on missionary work. A question was asked - what are the reasons missionaries go on missions. I thought about the reasons I went on a mission. Then I realized something. There are times in my life when I just know I ought to do something, and I feel it is not only unnecessary but even counterproductive to ask why. Counterproductive because it takes away from the focus. Deciding to go on a mission was one of those times for me.
I can remember a few other decisions that were like that. Deciding to be baptised, deciding to get married to Sarah, and deciding to run. Even though I am inclined towards logical reasoning, I often insist on logical explanations, I work in an area where correct logical reasoning is critical to success, there are times when I am perfectly willing to cast man's logic aside recognizing that it is inferior to something higher that is guiding me.
I have had people call me "lucky" because of my ability to make a decision that yields good results without being able to explain why I made that decision at the time I made it. That would not be quite correct. Let us consider the following mathematical model. We will model luck with a function of time that has random values in the range from -1 to 1, -1 being really bad luck, the worst you can get, and 1 being really good luck, the best you can get. The luck component of life success from time t1 to time t2 thus will be the integral of our luck function from t1 to t2. It is reasonable to expect luck to be random over the duration of a sufficiently long interval of time - for every instance of good luck there should be an instance of bad luck of equal magnitude. Thus the luck component integral will be zero. I argue that if your "luck" function consistently produces integrals with the absolute value significantly above zero, you are dealing with something other than luck.
