It's easy to miss the sounds and smells of Mexico. All the country's bright colours and its lively people.

But to master Spanish is going to be more difficult than I imagined, with so many verbs and tenses. I think I grasped the basics, but it would be hard to become properly fluent in Spanish without being immersed in it on a daily basis. I don't even have satellite TV.

TEFL would be a good idea. Though there's not much point doing a course unless I'm going to live abroad.

What I really need is a bit more action. I should work and get fit at the same time. Not in a gym. Out in the fresh air.

As a lifeguard, I could save people and become a hero. A heroine. In reality, though, I'd probably fall off my perch with boredom looking at people swimming all day. Like watching a tennis match.
