Tired friday

Its real eye tiring doing 3D modeling and rendering the whole day. I think I did it more for the money than interest. Maybe it is 50% interest & 50% for financial gains. Have I realised that merely doing 3D computer stuffs can't go far? If that is, maybe that's a good thing happening. Is it because I have grown wiser and realize that there are more important things in life? Or is because of University education that natured me to be smarter, so to realize that doing 3D computer stuff is just a skills that doesn't required much thinking, so I can put my time into chores that are intellectually more challenging?
But I do realized that learning this skill can at least make me 3 meals a day, but this is not the kind of life that I wanted. I think I can sort things up, have a system of doing 3D rendering, that can be mass producible. Thus I am able to generate a cash flow. With this profit, I can venture into other business...
I think I talk much today with Z'S. In fact, I can think abit harder, sort my thoughts more clearly, answering him more intellectually. Maybe we should have a friendly challenge so that it can pushes both our limits. Friendly competition is good. Yah, I should reorganised myself and have a friendly competition with him.
