I agree. I think humans can never be contented. We can see that from the rich, where there is always a new technology/car/something that they need to have; or a better year in sales for the company. But it is as you said, it's how we tackle these setbacks/roadblocks/challenges that matter. If what one is doing isn't giving them joy, then maybe they need to find something else to do.
As for the computer, if you're not tech savvy enough, I would suggest having it checked first before buying anything. I think as long as the CPU isn't the bottleneck, then you can just upgrade the different parts. You'll never know, it might just be a dusty PC problem.
I wouldn't say we can never be contented my friend. I think it's a choice we can all make. I think some people can never be contented, that's true, but they could if they wanted to. The fact that we are talking about it tells me we are able to see the problem, step back and decide to make the best of the life we are living. That's already a HUGE step in the right direction.
The computer is getting a 2000 MB/S solid state drive. This should fix the write issue for video and audio recording. It will probably get replaced soon too as we are constantly rendering HD video.
You're right. I was generalizing too much. I guess it's because I haven't really met another person that's fully contented with the way their life is.
Glad to hear you were able to fix the issue. Good luck on the computer build.
