I came across your blog while reading Dan Shipper's blog which I came across while reading Lifehacker which I probably found during some random web crawl. I usually don't write to bloggers/people-online much but you seem pretty cool about receiving and answering mail so here goes. I am not sure where your usual readership comes from but I am writing to you from Sri Lanka, which would most likely in the minority when it comes to your readership. :)
Your interests seem pretty varied on your blog, so I was wondering, how do you choose your particular 'line' or career, or where you ultimately want to head. Ideally one would want to specialize in something, but when your interests are varied, how do you figure out what you want to be. In various times of my life I have been interested in the pure sciences (Physics, Chemistry kind of stuff), computer science, I dabble in some photoshopping even though I am not great at it, I like music even though I am not great with an instrument, I like the idea of programming even though the thought of becoming good at it is too daunting, I like writing, even worked a bit on international relations, but haven't come across something I can devote myself to. It would be nice to find my calling before I grow old and die.
How would you choose where you want to go with your life if you just like everything?
Sleep deprivation is bad.
Don't try it, don't do it, it's bad for you.
