Do you go with the flow, or are you a planner?

I've realised how unplanned I am and I'm not sure if its a good or a bad thing. My friends compliment me for my randomness, and how I'm a free-being, but then they are all really scheduled and know what they want to be doing at most times of the day. I feel like planning things gets really overwhelming for me so I tend to just wing it most of the time. Does anyone else feel like this? or if you're a planner, got any tips?
