Not really. I think one reason koans are general and kind of vague is that everyone's specifics are different and advice that works for some people may not work for everyone and may be exactly wrong for some.
Once, my then girlfriend was telling me that she was having trouble at work and always felt bad asking people for help. I gave her advice that had really helped me - which was to not worry about it and ask, ask, ask for help! It's the most efficient way, and all that.
My natural inclination is to never ask for help and figure it out myself. That can wind up taking me ten times as long to figure stuff out, so for me, really pushing to ask for help balances my natural tendencies and, if I try to ask for what seems like lots and lots of help, it'll wind up being about right.
My then girlfriend, on the other hand, was already inclined to ask for help. She was rightly worried that she was annoying other people and asking for too much help and I, though well meaning, gave her exactly the wrong advice and pushed her to keep doing exactly the wrong thing. The advice she needed was the exact opposite of what I needed. This is a specific example of how you can't really give advice to people without understanding them and their problems.
To go back to koans (which I quite like) - if you meet the Buddha, kill him. Meaning: you can't listen to other people to find enlightenment, it has to come from within you. Other people cannot tell you what you need to know, only you can do that.
And, of course, I'm not an enlightened guru living a perfect life or anything. I try my best. I think about problems and take steps to solve them.
