I love good advice. Why? Because I love efficiency. Good advice spares me from costly, inefficient mistakes that other people have already made, freeing me to make my own spectacular, brand-new mistakes. Of all the advice I’ve received, this is my favorite:
He who walks among poopies gets poopies stuck to him.
It’s a nice reminder to choose friends and associates wisely, lest their metaphorical poopies end up in your backyard. It also warns of the need for situational awareness. Sometimes life's poopies aren't metaphorical.
Here's another one, courtesy of my dad:
Keep your workspace clean.
I'm the kind of guy who can absent-mindedly set aside a tape measure when I'm working, then spend five minutes hunting for it the next time I need it. Those little five-minute intervals add up, they're distracting, and they hurt the outcome. But if you think of the workspace as part of the job, investing a few minutes here and there to clean and organize as you go, there will be a lot less cursing.
One more, courtesy of my mom:
Pay a little extra toward your mortgage each month.
If you have a mortgage, do yourself a favor and look at your amortization schedule. Ask your lender if you don't know what that is. Applying a few extra bucks to the principal each month magically reduces total interest, increases equity, and shortens the length of the loan. Soon, you could be like me and own 12% of a middling-quality tract home.
