CCNA certificate update

I got the CCNA certificate a half year after I began current job. For the beginning of this September, my CCNA is going to be expired.

So far the knowledge I learned has made little difference in my work, but studying for it was a good opportunity to obtain basic knowledge of TCP/IP networking. I plan to update the certificate in a few month, and I'll have to review some knowledge I may have forgotten. Moreover, due to the update of the test, I have to learn more about IP version 6 than I studied 3 years ago.

Thanks to many online and offline resources, like practice quiz sites and simulators on the web, I can learn the skill required for the test much easier than I only read textbook and just imagine what tests and the appliances I have to know much of.

For the beginning, I plan to buy the guidebook for new version of the test, available on Kindle.

Am I going to be disadvantaged forever because the skin of my face and my head is too dry? This is one reason why I thought that I wanted to escape my country when I was 11 and 25. This made me learn some foreign language. However, I'm learning that overseas isn't so good as I dream about, especially as long as I go to public school. W...

It's my lack of confidence that is to be beaten

Autism, is it something to be removed? Or is it just another type of human being? I can't answer to this question. I, as you see, have language, and have a job. Although my struggles are real as well, I hear that there are a lot of cases of struggles many thousand times than mine. Ones who don't have language, or with serious behavioral problem. Although my behavioral problems, mainly social awkwardness, I can't answer the question whether autism is something that should be beaten. Instead, I can answer one question. I have to beat my lack of confidence through long struggles, if I want to succeed.
