Unexpected source of wisdom ...

For some damn reason, I cannot access my SingNET email. However, saw an email subject downloaded to my mobile phone and I was rather surprised that its something I should probably learn. The email was sent as part of my subscription to St James Power Station for their event updates and this is what I saw:

"A retentive memory may be a good thing, but the ability to forget is the true token of greatness"

I did not get to see the rest of the email yet so I have no idea what is referencing to. However, the subject of the email alone is quite an attention grabber.
