Who Or What Holds Power In My Life?

Do you ever just sit there and imagine what your life would be like 20 years from now? Do you ever wonder if the choices you make control the outcome of this picture? This idea is the only thing that I let hold power over me, and sometimes people say it's not such a good thing. The fact that every wrong or right move I make is what determines my life's outcome scares me to death. I always ponder my decisions before I make them, wondering whether or not the result of this choice would benefit me in any way. Its like this.. "Picture yourself walking along a straight path cut into a long field of grass, you come to a section of the path that has two decisions: right or left. You don't know this, but if you go right you will fall off a cliff 50 feet up, and if you go left you will find your home and your future will turn out exactly how you want it to." The choice is all yours, so you find yourself going right, headed straight for the cliff. Since you went right you will never know what your life could have been like if you would have gone left. Scary, huh? I think of my options like that, and sometimes I go the wrong way. I think that every mistake I make is another step towards the cliff, and sooner or later it will be too late to turn around. I hear all the time that I live too much in the future, but it's hard not to when it is the outcome of everything I will ever work for.
