It is not a mistake to commit a mistake, for no one commits a mistake knowing it to be one. But it is a mistake not to correct the mistake after knowing it to be one. If you are afraid of committing a mistake, you are afraid of doing anything at all. You will correct your mistakes whenever you find them.
Virtue knowing no base repulse, shines with untarnished honour; nor does she assume or resign her emblems of honour by the will of some popular breeze.
[Lat., Virtus repulse nescia sordidae,
Intaminatis fulget honoribus;
Nec sumit aut ponit secures
Arbitrio popularis aurae.]
What an investor needs is the ability to correctly evaluate selected businesses. Note that word “selected”: You don't have to be an expert on every company, or even many. You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.
The notion that somehow as a consequence of me knowing somebody who engaged in detestable acts 40 years ago, when I was 8 years old, somehow reflects on me and my values doesn't make much sense.
What intrigued me more than anything else was finding out the way in which everything, all of creation - all of it! - was held together by invisible chemical bonds, and I found a strange, inexplicable comfort in knowing that somewhere, even though we couldn't see it in our own world, there was a real stability.
Knowing that I am different from the body, I need not neglect the body. It is a vehicle that I use to transact with the world. It is the temple which houses the Pure Self within.
