If you'd asked me five years ago if it was possible to do music production on the road, I would have laughed at you. Thankfully, technology has come a long way, and there's very little you need to produce music outside of a laptop and whatever instruments you play. There's a case to be made that you don't even need physical instruments, but I think they're worth it for the 'realness' and feeling they can channel. Most of the time, though, I don't need more than a laptop and my trusty Sennheisers.
I prefer to work with as much of my own recording as possible, so when I'm not going directly into my interface with a guitar or instrument pickup, I'll rig up a temporary isolation box to mic my source (post coming soon). Here's my basic setup for recording vocals:
The point is that so many people I talk to seem to fixate on gear or the space they're working in, and that takes away from the music. The less time and effort it takes to capture ideas and then polish them, the more quality work you'll produce. If you're holding back, or worse, never recording because something isn't perfect, it's tough to stay relevant with how fast the music lifecycle is these days. The trick is to know what can be fixed later versus what has to be right in the original take so you don't waste hours on little things that aren't important to the end result.
I'm also a huge fan of the Pomodoro One app to keep on track. It's a timer that you set to help focus for a short period of time, and then it tells you to take a break. Pretty simple, but in practice, it keeps me productive and forces me to break up my work and avoid burnout.
Keep it simple, and don't build up obstacles to doing the important stuff!
