I don't really look at the charts at all. If anything, I try to out-do what I've done before. I try to make music that I like and I trust my own judgement with what will work with a wider audience. If you compare yourself to the charts, you lose perspective on what you're doing and why you're doing it.

I travel with a bunch of battery packs because I don't always have time to charge my phone at the hotel room when I'm traveling. I always change them, so I never run out of battery.
