Some days I wake and can really relate to Murtaugh in Lethal Weapon, sadly more frequently as time moves on.
But some days (still more often than not) i feel like the 20 year old who could take on any challenge the world throws at him (in the computer realm, lets not kid ourselves).
The ratio between these scenarios is changing, in a manner I'm not happy with but I feel really good about still taking joy and having fun with (most) of my job.
