I often struggle with complacency and getting comfortable, so when I asked my mentor how to fix it he told me about Amazon's "Day 1 culture." (Picture attached)
The idea is basically that you treat every day as day 1 of your business. So no matter what happened yesterday, or what's going to happen tomorrow, you treat every day like you're just starting your business and keep that momentum. I'm starting to implement this mindset to see how it helps.
