Regex Training - Linkedin

I have always been able to get done what I needed to do with regular expressions but it always took me way to long when I needed to write them.    I knew it was a problem of mine and I figured I would take the regex LinkedIn training by Kevin Skoglund to help me get a better understanding of regex.    It was a very thorough training and Kevin makes it easy and understandable.  I felt like I really moved through this training but I still have a concern that if I don't use it more often I will have problems remembering it.  I did take thorough notes and Im hoping that for the small portion of the training that I may forget, that my notes will give me that reference point to to quickly recall and write the regex that I want to write.  

I definitely should have done this training 15 years ago and made sure never to forget it.  There are so many uses for this training and I am pretty sure it will turn out to be invaluable going forward.
