Here's an oldie but goodie - and something still relevant to your career today.
There are two bulls high up on a hill, looking down at a herd of cattle below.
'Hey', shouts the young bull, 'Let's run down there and make love to one of those cows'.
'No', says the old bull wisely, 'Let's walk down, and make love to them all'.
Moral - Old bulls aren't necessarily old fools.
