Hey Neo. I can relate. I was once in an eerily similar state of mind. Studied philosophy and theology for
years trying to expand my mind, answer my questions and come to a view that felt right and... complete. After awhile I started to pick out views I agreed with from all these schools of thought. Started living by my own philosophy. To my amazement, the thing I created was very very similar to Zen Buddhism. When I read the first book on Zen I was blown away. So, I found it very easy to slip right into it because I was kind of practicing before knowing I was practicing haha.
My ego, fed on speculation and intellectualism for almost three decades, has rebelled against zazen at times as well. I find it's beneficial to show myself kindness at such times. Visualize a mother consoling her infant. "It's okay sweetie, you're all right. We're just gonna sit now, okay?" I take a few deep breaths, and envelop myself completely in mindfulness when preparing to sit. Then, the ego settles and submits. Like a child afraid of the dark who's been lulled into sleep. If you're interested, this
upcoming column written for the local paper might be useful.
In regards to striving, learning, growing and all that I can only suggest the view of being the moment. If we drop all thoughts of, "Doing this for that reason," "I hate this I wish it was done, " "I love this, I wish it would never end," and just focus on the sweeping when we sweep then it's possible to truly be immersed in the motion of sweeping, united with it. Then, the floor being swept and clean is just a fortunate byproduct. This is anything but stagnant, this is the way of unadulterated equanimity, emotional beauty and satisfaction. The grass doesn't think of growing, it just grows. With this there is unconditional appreciation, which is the essence of enjoyment. That's my take on it at least.
