Struggles

So where is the happy medium in life? I am always thinking about the balance between learning new things and specializing. Between eating whatever I want and as much as I want whenever and only eating what I need and what is good and healthy. Or between exercising and being in good shape or enjoying your body for what it is. I think these struggles come down to a struggle with who I want to be. I want to be a quiet person, allowing more times for my thoughts, but it is also my thoughts that could drive me crazy. But I also want to be a person unafraid to express her opinions, confident in what she believes. I want to be an accomplished musician, but also want to be well rounded (how is this possible if I must put all of my focus on music?). I care so much about people, how they are doing, what's new... but when do you let go? If a person has betrayed and abandoned you, yet you still love them, what do you do? I think... at least I hope that these are the struggles of everyone in life. Does comfort and understanding come from experience? Or does it never come... do you just use trial and error, maybe gaining some understanding from that? Perhaps there are no answers to our questions, only thoughts to complicate them.
