Is it really too early to start thinking about your future?

I remember being in the 6th grade and wondering if I'm having thoughts about my future. I remember questioning myself and doubting the certainty of these thoughts. But, what I wish someone had told me is that it is never too early. These are the thoughts that transform into ambition and passion for a career. Interest and passion come together at an uncertain age; it is something that is out of our control. Why is it that we always find ourselves questioning our hopes? Why does an incline towards a career have to come with an age restriction? Back in the 8th grade, I first learned about the fundamentals of Psychology. My mind immediately directed myself towards it. I came across several people doubting the certainty and assurance of it, simply because of my young age. Age is constantly associated with the likeliness of being certain, and I struggled to convey my deep interest in the subject. Now, as a junior in High School, I find myself closer to pursuing that career than ever before. Each of my goals and ambitions lie within the lines of Psychology. An underestimated quality of learning what you want to do early on is the sense of conviction and high motivation one experiences to go through with the plan. Despite of whether that plan is seen through or not, the passion and motivation is likely to carry forward to whatever it is that your "new plan" includes. I have learned the power of my thoughts and inhibitions, even as a maturing individual. My thirteen year old self thinking it is what makes my sixteen year old self want to achieve it.
