Hi NAR,

Maybe that's what "they" call the zone:  Being concentrated but not trying.  I try not to get into the popular lexicon about feeling good, meditation, or other such stuff - it's just too trendy for my taste and I still have a huge aversion to anything called meditation because of the cult.   Anything "meditative" just turns me off big time.

When I'm doing something that I love to do, I find that my concentration becomes very vivid and pronounced.  I find that I become focused upon the thing I'm doing and my extraneous thoughts fade into the background.  Zeroing in. I also can observe that process happening or not (the thoughts fading and/or stopping).  It doesn't matter either way, as long as I'm happy doing what I'm doing.

The actions may be something like singing, which makes me feel really great, or when I'm doing something singular, simple and repetitious like planting seeds or plants in my garden or even pulling weeds -- even repotting houseplants does it for me.  Or, when I do anything mechanical, like working on my car, or exploring how to fix something else that's mechanical (I love fixing things!) I concentrate more than usual, especially when I take my computer apart and have to keep track of all the parts and pieces.  I love that kind of concentration.  It feels so good and those are times I cherish being alone too -- no interruptions!.  That's the reason I like being a simple person living around a lot of natural beauty I guess -- I admit it, I'm pretty spoiled.  Hey, fishing does it too!  Or walking up and down my road, even -- too cool for words. 

Now that I think about it, there are lots and lots of activities in nature that cause more concentration, focus, and a good feeling for me.  It's so much better than anything I ever got out of "Knowledge" that's for sure.  I like being outward-and-doing and feeling good, rather than being inward-trying for something undefined.  Plus, I get something visibly accomplished!!!

But, that's just me...
