"I hate inconveniences of travelling and after I have travelled I quickly forget almost all of the things I've seen or experienced. Nearly same amount of memories remain in my head regardless of whether I've been into 3 or 30 places."
Not me. Are you traveling to the same areas? I can certainly say traveling through China gave me many new and interesting memories.
"You don't buy kids. Kids happen. If I had kids then probably I'd need more money than I do now, but kids didn't happen to me yet."
yeah, well, that's not a good way to think. The people that I know that just let kids 'happen' now have very little options because they have an extra mouth to feed without thinking about the extra income that this requires. It's also not a good thing to bring a kid into the world only to live at or below the poverty line. Another consequence of letting kids "happen".
"Every hobby also requires time. And time is neatly eaten up by all my hobbies that don't require money and by some work I do."
So you your work is your hobby. This is fine. But it's not the case for a lot of other people. Work has also been my hobby for 15 years, but there are so many other things that I've found in the last couple of years that require money.
Aside from programming and exercising, most hobbies require money.
"Especially because to fund the new hobby I'd have to increase time devoted to work and reduce time devoted to current hobbies further."
This is why I only get into businesses where my time is not directly proportional to the money I make. It's a losing battle.
"My freedom does not require a lot of money. I'm 33 and I never had a boss."
It's because you're living like a 21 year-old. It's fun, but loses it's appeal after awhile.
"I could travel much more than I like. I could get a house. I could replace my hobbies with new paid ones. I could have kids. But isn't this a bit much to just get "money hunger"? I want to increase my motivation but not at the cost of doing things that would tire me to tears."
I feel like this is like trying to describe an emotion to someone that has never felt one.
In addition to the freedom that money provides, I also want to help out people in my family that are less fortunate/don't have as many opportunities.
