Now, I'm starting to see cranky on the horizon for me - I'm 30, so no longer really a smartass kid... but this (former) smartass kid has had a great many moments dealing with grumpy older dudes twice my age who think they know it all but have been caught off guard by smart suggestions and ideas by yours truly. I've also spent plenty of time cleaning up the messes made by so-called "experts". That being said, I know how exasperating it can be to have something suggested by someone younger or substantially junior in the workplace, I've been there too (as I said, I'm 30, so not really wet behind the ears anymore). It can be hard to know when someone young is smart and knows a thing or two, but I'm finding its even harder to remain humble as I get older, especially if you're particularly good at something. ...not trying to tell anyone to be humble or anything, more just thinking out loud, and asking for advice on how to BE humble as I get older. I'll have to ask my old man about this, he's managed to remain incredibly humble despite being particularly intelligent and skilled in his field.
