Are you striving for something big? Something where the path isn’t clear, but the reward would be huge? In other words a goal that’s worth pursuing?
Whatever your process is, you need to let go of what you know. When JFK said we’d put a man on the moon in the next 10 years, he certainly had no idea how. I’m sure he also had many people telling him this is impossible. The key was that scientists had to just let go of what they knew in order to move forward, and eventually they did.
Whatever it is that you’re striving for, surrender to the process. Don’t keep clinging onto what you know, nothing big will happen from there.
