Check the local rags and mags: As I mentioned before, most SE Asian countries have English-written guides. That's because in a number of countries there, there is already an established community of expatriates. If you are looking to just find your bearings and want a safe bet on places to go, pick one up.
The second reason is memories! Think of all of the adventures that you will go on if you are in Africa. Even if you are the conservative type you will still stumble across something exciting and meet people that enjoy the same things that you enjoy. Also, you don't have to go to Africa, you can travel anywhere that tickles your interest.
First reason. The people that you meet are completely different as you get further from home and further from places with media influence. If you are a good person at heart then you will run into hundreds of other good people, along with fellow travelers that can guide you in directions that no one else could.
So that is four concrete reasons that you should travel the world. If you still are not convinced then do a quick google search and you will find hundreds of pictures, videos and stories of people just like you and I having an amazing time traveling the world.
When you can, take a bus or train: When it comes to budget traveling, this is the way. Night buses get you from one country to the next for next to nothing, although they do take longer, no doubt about that. Roads between many destinations are well enough to travel, although there are going to be bumpy rides. None the less, when you need to do it on the cheap, this is the best option.
