Start now: The case for having a bias towards action
Don't let fear, lack of experience, resources, or direction hold you back.
Successful people take action. Learning is great, but if you're addicted to it without achieving your goals, you're just wasting time. As Robin Sharma said, knowing what to do and not doing it is the same as not knowing what to do. So stop reading, watching, and enrolling in courses. Apply what you learn and track your progress!
Plan and think, but you have to act. Overthinking won't give you all the answers, so you have to take the plunge at some point. So the question is, do you need more information or already have enough?
At some point, you have enough. Don't let fear, lack of experience, resources, or direction hold you back. These feelings will never disappear until after you start, so start now.
