Decisions Schmecisions

A group of friends are trying to make plans on a Friday night. What do you want to do? I don't know, what do you want to do? What do I want to do? Shoot myself in the head. Options are discussed for some time, until one person commands the attention of all in the room and makes a decision. They may pick an option previously mentioned or they may come up with a completely new idea and everyone looks happy or they fake it well. My personal opinion is that everyone is relieved that someone finally took charge and it only took 2 hours.
I can make decisions at work. I assist clients in making decisions everyday. What doctor to see, which toothpaste to buy, how their funds are distributed, and the list goes on and on. Then last week my supervisor asked me to choose the restaurant for our February birthday lunch. Panic hit and I've yet to make a decision. Why? Most likely because I don't want to pick a place someone will dislike and, well, because for the most part, I don't care where we eat.
Let's delve deeper into my indecisive life.
According to my brother-in-law Travista, I rarely make decisions because my dad does everything for me. Oh how I wish he could see me in a setting away from the family. Wait, maybe he would still think I can't make decisions. Let me get my dad's opinion on that.
How can I make decisions on behalf of the individuals I work with, but struggle making decisions in my own life? I'd like to think it's not due to the fact that I don't care enough about anything to make a decision, but I'm beginning to wonder.
