These 2 weeks had been most exhausted event for my brain. While researching designer class, I found something new and yet confusing methods to study. Design time component has a very wide scope to begin with, and it seems like one method can spread to another method. Sometimes I can be very frustrating. Once I got a small solution or step, that step always connects to another 2 or 3 problem that had to be solved. I wonder how much time I have to spend to complete my current home project. Luckily, my work had been on simulation stage, which mean, I have more spare time to observe and studying articles while doing a little design to my next project. Now I start wonder, since I have to put a lot of effort to my home project, maybe I should start to commercialize it? It maybe worth some money.
