This week, I have decided to conclude my work with my client. Reason: study for my CCIE.
Am I obsessed? Am I doing the right thing? Nobody knows, except myself 
Today, I finally meet with the real challenge of CCIE lab: multiple routing protocol. It hit me quite hard today and somehow I was amazed that the solution is simple yet challenging to be implemented.
I was tickled to face this kind of challenge long time ago when I decided to be a system/network engineer. Surprisingly after deciding it, many years after, I have forgotten that I would like to be a aystem/network engineer. MY former supervisor said to me on something and I hit me with a shock: "Hey, I am a system/network engineer now". But that's acoording to him. I am still polishing myself to a better system/network engineer that can provide solutions instead of reacting from problems.
Here I am now: part-time instructor (teacher???) and part-time CCIE certification candidate.
I have discussed this decision with my other half as well. I inform her that by taking this decision, my income source would be halved (or quartered???) and I will depend on her financially. Since I am not owrking other than my teaching, ideally I would not spend more money
I am still human anyway, more money = more spending 
Tomorrow I am going to meet a very important person that I called him as guru/ mentor and ideal person that I considered him to be a role model of a succesful person. He is not rich as in amazingly rich, but he surely fit into what I always wanted to be: a techy businessman. Maybe I will tweak myself as geek businessman.
Somehow I started to like hearing the word 'geek' for me.
Come on brain, let's work together to overcome this CCIE lab. Creativity is a must and I have one secret: use your left hand if you are right-handed.
