Been busy, hence the 'late' response...
By your examples one might conclude it takes a very short time to make some principles yours pretty quickly. This makes me wonder if practise within the art is efficient enough. I mean I could be training Aikido for ten years, do a side step to something else for a few months and then understand some principle and continue....
I know this happens and realise there are benefits, but still it makes me wonder why this progress cannot be made within the initial art.
I suppose it has something to do with mindset...change of food kinda thing.
What do you make of this?
The truth of the matter is that other person or teacher has a perspective that you had been unaware of. Thus suddenly the thing you have been trying to get to grips with makes more sense and thus becomes easier to learn.
