Everybody always wants more, it's how it works. Because you get a 2000k euros salary, which is enough to live on your own, you don't want more? Especially if you can definitely have more with your abilities?
If you're a pro football player, don't you want to get faster and smarter and win even more matchs and titles?
If your company owns 45% of the market, wouldn't you want even better?
You can be satisfied, but never entirely satisfied if there can be better, especially when something is underperforming. I'll never understand people who're "satisfied with what they have", especially because they're usually the ones complaining that others are complaining and like to remind others how better they have it compared to them. I mean, right now you're complaining about a not so important, right? Why would you? Why can't you just move on?
