Favorite quotations:

Think different ....deep..... and ......wide.....always

I skate to where the puck is going to be, not where it is.

Procrastination is one of the most common and deadliest of diseases and its toll on success and happiness is heavy.

You really dont understand something unless you can explain it to your grandmother.

The one who laughs last, wins it!  the game is still on.

An opportunity is an opportunity only to the one who is prepared.

If it doesn't work, then make it work!

If you want your children to be well, then do not teach what you can see and can hold, but teach what you can not see and can not hold.

Can't avoid it? enjoy it!

It's 10pm now. Did you hug your children and research today?

Anyone who has never made a mistake has never tried anything new
