I long ago started keeping notes on what I learn for just this reason. I mostly use kjots for this, which lets me organize them into categorized pages. But of course even a paper notebook would do.
Another option is to post your findings here, under the success stories forum, say, which means others can benefit from it as well.
The only problem I still have is when I don't think something is important enough to keep track of and so don't bother to file it away. That's when I inevitably forget exactly how I did it and wish I had.
