Have you ever wanted to achieve a goal and ended up doing lots of research on how to achieve it? As you learned more and more, it seemed you knew less and less. That is because when you learned a new concept, you found that there was a lot more to know about it.
Usually, people think they need to get more and more information before trying a new idea. There is nothing wrong with learning a lot, but when you let learning get in the way of doing, you will never get going.
One of the best ways to learn is to take action and learn from the results that you get from those actions. Don't be afraid of not being perfect and just take the first step. You will go further than those who are still in preparation. It's good to be prepared, but overpreparation in trying to reach a goal won't get you results. The knowledge and skills that you will need will be picked up along the way.
Learning more is great but if all you're doing is learning and not taking action, it's time to change that. Just take the first step.
