My decision about 1 year ago to start doing training was a strange move for me. It was totally new and scary field for me, but like I said at the moment, according to my experience all change has been for good. I think I can trust my intuition.

I found a short article about How we learn which summarizes my point of view after 5 courses.

10% of what we READ

20% of what we HEAR

30% of what we SEE

50% of what we SEE and HEAR

70% of what is DISCUSSED with OTHERS

80% of what is EXPERIENCED PERSONALLY

95% of what we TEACH TO SOMEONE ELSE
