Valium and Xanax are your friends for long journeys--Valium and Xanax are sedative-hypnotics in the benzodiazapine family. I didn't even have to look that up. When you take them you will either fall asleep or drift into a pleasant daze. Either of these makes a long plane, bus, or rail trip infinitely more bearable. Most countries require a doctor's prescription (or good connection) so don't be an idiot and try to bring them across borders.
No one cares about your travel blog--By travel blog I mean a blog or series of emails where you provide pictures and long written descriptions of places you've been. It might hurt to hear this, but your family and friends will either be apathetic or bitterly jealous of your travels. Sure, there will be one person on the outer periphery of your circle of friends who seems really enthused, but let's face it, there's a reason you don't hang out with her very much.
The other thing is that this isn't the 16th century and there's nothing unique about visiting places halfway around the world. There was a time when Thailand was exotic and mysterious*, but now it's just a mass tourism destination like any other. Hell, even my sister's been there and she likes Dane Cook. Unless you're visiting North Korea or hitchhiking through Iraq, people just aren't interested.

Get the business card from wherever you're staying--Sometimes you can't remember the name of the place you're staying. Sometimes you're too drunk to pronounce it. Sometimes the cab driver doesn't know where it is and needs to call the front desk. You don't want to be wandering around trying to remember where you checked into a few hours ago.
Get lots of passport photos--The last time you needed passport photos you probably got the cheap set of four, used two on your paperwork, and shoved the others into a drawer. This is a mistake. Living in another country (or just travelling abroad) will burn through passport photos like a fat guy eating Cheetos. Any time you need to get some paperwork handled (including visas), you'll generally need to provide at lease a pair of photos. God help you if lose any travel documents. It's usually only marginally more expensive to get 16 (or more) photos instead of 4, so make sure you take advantage of the opportunity.
