I learned this several years ago when I belonged to an association. The members were very friendly, helpful, and full of advice. I took in everything everyone told me and tried to apply it all. It did not work.
I realized that although everything they gave me were “gems” to them, because these things had worked for them, not everything was right for my situation. Of the advice I received, some could be considered precious gems and worthwhile to implement quickly. Some advice was more in the line of semi-precious gems, advice that was worthwhile to implement at some point, but not a priority at the time. And some advice, for my situation, was gravel and best discarded.
I spent quite a bit of time and money trying to implement everything. With the benefit of 20/20 hindsight, I realized that it would have been better had I analyzed every piece of advice first to see if, for me, it was a gem or gravel.
When people offer advice, be careful not to use the gravel. Do not discard everything without analyzing it first, however, because there probably will be some gems in there somewhere.
