Hi there buddy,
You are - and Nike was - right:
Just Do It
There's talking and thinking about something and actually doing it. It makes a huge difference. Although the former is often needed too.
One example:
I spent so many years studying, watching and talking film(making) but I didn't make a single short. It was depressing.
Activity versus passivity:
Even though I know and have known this for a long time myself, I keep getting back to a passive mode and there's always this gnawing feeling inside of me that I should be more active and that what I'm doing is a waste of time. Nevertheless, I'm probably way less passive than most people, haha
I am getting there. And awareness is spreading. Nevertheless, I should learn to not feel bad about being ( more ) passive every now and then. In the end it's all about balance. Rest is needed too. The thing is, what we often do when we need rest, does not necessarily relax us.
Let's not forget to keep breathing and also focus on the moments inbetween the breath for the necessary pauses ;>)
