Hehehe Animal, I'll better practice then... no watermelon-throwing tho, rules are rules
In my opinion, we should first complete what we have (ISS) and then try other projects.
The moon is a very probable next destination, since we will need serious practice if we want to send a manned spaceship to Mars. Everything from hydroponic gardens to sustainable energy sources for a Martian base will have to be first tested on the moon.
We are talking 2020 or even 2025, though.
As for being an astronaut, I'm pretty optimistic there. Check X-Prize, for example. It's a multi-million dollar prize for the first company that designs and operates a sub-orbital vehicle capable of putting people in a flight that would take them to a LEO and then back to earth.
While it's not actually being in orbit, it's a first step, and there are many companies now working on it. I hope to see commercial flights in no more than 5 years.
BTW, I am going to fly in the Zero-G A300 again this september, I'll be posting some pics
