From time to time i have a confidence crisis with regard to my own knowledge.I am in such a phase now.Have happened many times before.Started reading the Cisco Press book and watching CBT Nuggets videos for the 642-901 exam a few weeks ago.Could not remember some basic stuff from the CCNA.Trying to say to my self that you have to work with it on a daily basis to get to know every detail.I am just studdying and currently unemployed.Anybody else have these confidence problems or it is just me?
