People are looking for certainty. The more complex the world becomes, the more people look for people to give them certainty and tell them what to do. During the past few years of actively thinking about this, there is one thing that I have accepted: certainty is not out there. There is not one strategy to follow, and that's OK.
My dad was a very quiet person, and unbelievably tough. But my grandmother gave me my first look at negative thinking to bring about positive results. When I was just a little guy, anytime I came to my grandmother and said I wish for this or that, Grandma would say, 'If wishes were horses, beggars would ride.'
