Planning is great, but don't just think or dream about what you want to do. Just do it. Effective planning means doing your research, improving your skills, and taking action. Good plans ensure you’re constantly taking action, not just continuing to plan.
Note taking is a useful exercise sometimes, as long as you then take action on those notes soon after. You can keep learning and learning. But you're best off just starting to do what you set out to do, then learn as you go.
Too many people get stuck at the learning stage. You have to continuously take action on what you've learned to gain any momentum. Yes, highly successful people never stop learning. But the most important thing is to never stop doing, too. That's the key.
Make a plan that you can immediately take action doing. Then, win or lose, learn from the experience. Make a new plan to take a step forward. That's how you build momentum and work towards success!
