Yes, yes, I know. ALL of the travel tips tell you to travel light. Pack one bag. Make it small enough to be carry on. That way you can take your laptop and your suitcase on the plane with you. They don't get lost. You don't have to wait to get your luggage at your destination. You can just waltz through to get to the front of the taxi / rental car line.
I used to be like that too. That system works well for the occasional over night or short trip, but when I was spending months commuting on the first plane out Monday morning and returning on the last flight Friday night, traveling light lost its lustre. I don't like eating alone. I don't like watching TV. I wanted to feel like I was accomplishing more than just logging another 40 hours on my client's account. I wanted to do something for me while I was away.
If you feel that way, then try taking a little of your personal life with you on your journey. In my case, it was my trumpet. Wait, before you freak at the thought that the guy in the hotel room next to yours might suddenly start wailing away in the middle of the night, I was using Yamaha's Silent Brass system, which completely deadens the sound and lets you hear yourself through earphones. In all my years of traveling, I never got any calls about noise. So yes, I packed my trumpet in my suitcase and found some sanity in my crazy life as a road warrior.
