There is no other teacher as the one where you is teaching you .

Witch is the observer in you that can see the stumbling and trying of others and even the self .

I by no means are a teacher , people you learned from just gave some good useful info . In the end i thank myself for being able to tie my shoes , yet still respectful towards the ones that shared and showed it to me .
They can tell you all about swimming , in the end you have to learn it ,.. yourself . ;-)
