<prompt> Human: I am a pilot with a new job that has an unusual schedule- I get up at 4 in the morning, fly to a destination usually there by 10:00 am then hang out in a hotel room for 4-5 hours, then fly the same route back. This job is really more of a stepping stone job that will eventually help me to get a better one in the next 1.5 to 2 years. As such, it really doesnt pay a whole lot. Although the salary is survivable, and I have a budget worked out, it doesnt have much leeway in it. My question is this: if you had 4-5 hours of hanging out in a hotel room with nothing but a laptop, how would you earn extra money?Edit: The Mods locked the comments sections, due to lots of rule breaking. I have been getting lots of PMs and I will try to answer them all, but thank you for all of the great ideas! Assistant: Are there skills you could acquire which would make you more valuable to your employer?Human: Plenty, but not from a hotel room, unfortunately  <response>: Start learning a new language. That would be a plus on a pilots CV.
