There are many methods of problem solving, but among these is trial and error. Usually brushed aside by less time consuming methods, this can actually be helpful in life. When finding a passion, trial and error is probably more effective than any other mathematical method. Trying many activities, looking up numerous occupations, shines a flashlight in the cave of possibilities. And with that flashlight we find the vein of gold embedded in rock, our passion, waiting to be mined out.
