I’m posting this question, not looking for any specific answer, just a general idea, of how you deal with certain skills that are very important to know but that you may not get to use very often. I’ve found that in my career I have studied and learned an amazing amount of information, but that I’ve also forgotten quite a bit of it due to it’s rare use. In a lot of cases the knowledge comes back to me when a situation presents itself, but in others I do find myself having to go back to reference manuals or the internet to give me a few hints. I hope that I am not the only person that has to do this. So I’m asking you to post what you do, if anything, to keep yourself updated and reminded of these skills..and also, is it really necessary that you always keep these skills so fresh in mind if you don’t use them very often?
