I was listening to a Tony Robbins video earlier and he made a great point: when you're facing some difficult challenges and can't figure out what to do, take a massive action. Do something drastic that flips everything on its head and see where it takes you.
One of my favorite books is titled after that idea.
Usually when we feel stuck it's because we are trying to do the same old things, and hoping something changes while we stay stuck on stupid. Make changes to get changes. It sounds quite simple, but we all need that wake-up call every now and then.
