In most of my friends who enjoy traveling I see a certain histeria, a mixing of their expectations with reality that is really uncomfortable to be around (like hearing "this is paradise" to a landscape that is really familiar; like "checkpointing" by taking pictures of landmarks and signs and trivial activities everybody does; like calling fast-food "wonderful" because it comes in a pretty plate from a waiter who doesn't speak your language; etc).
In my case, I find that feeling of uncertainty on arriving at a new country to be exhilarating. I feel so comfortable in my day-to-day life, that it's rare that I really need to think much about my environment. Whenever I travel it makes me think about my existence a bit differently; that is the real value I get from travel.
Travel can be cheaper than being at home, depending on where you go and where you live. And in response to your fear of being robbed; just don't travel with much of anything and get travel insurance. The worst that can happen is that you'll end up without a passport somewhere and have to go through some bureaucratic process to get a new one.
I find traveling to be a great way to expand your view of the world. Living in Bangalore for 6 weeks changed me forever.
That's exactly why you should travel to learn about the world outside of your immediate cocoon.
Most businesses you want to work for will also develop libraries/frameworks that are used in house. Or they might develop applications which consist of more than just plugging libraries together.
Do other people feel the same way? Obviously future medical advances might change my mind on this, but I would prefer to die around 80...
I know the cliche is "you feel that now when you're young, you wait until you're my age and say that again"... but I suspect that when I do reach that age, my main reason for not euthanizing myself would be not wanting to upset people who know me, rather than because I actually want to live to be 100 years old.
I want to live as long as medically possible, as long as I am not a vegetable or in horrible pain.
100 years, 200 years, 500, 1,000. I just don't think I will get bored of life.
For example, a good friend of mine works at a mutual fund as an analyst covering banks. For him, his job is already highly levered to the performance of equity markets.
Rather than invest in more stocks for his personal account, he's been looking at places where he can diversify and earn a decent return. For example, he's been investing in rental properties. Another friend works as an oil & gas ibanker, his investments are mostly concentrated in commercial real estate deals.
This goes for everything, girls, goals, jobs, ideas and even food =)
If you know what you want, you'll never go wrong. Most people don't know what they want, and spend forever trying to find it. But then it's too late.
