After getting my masters in 1982 and then half defending PhD I did not do any certs. To me it is a total waste of time. When I need something I do not know I always find enough info on how to solve a problem or guess it myself. Being a former scientist this is how I was trained. The last thing I need are some bloodsuckers charging me money for their failure to produce decent docs / manuals / whatever else relevant. Since I went on my own for the last 22 years I do not recall ever being asked for any certs anyways. I specialize in developing products from scratch with some hit an run jobs in between and clients just read references and rather long list of products I've developed. This severs me way better than any cert ever will. Of course the situation would be totally different if I've worked in some other field.
