No matter what you're working on, learning and practice are essential for getting good.
It requires practice to become a good founder, like anything else in life.
Think about some of the other things you might be good at...
Your job? The usual pathway to employment involves 7+ years of training throughout school, university, or some sort of employment training ground.
Sports or hobbies? If you’re good at a sport or some other hobby you would have learnt the skill and done a decent amount of practice. If you're a pro then you would have a coach and practice daily.
If you want to get good at something, you need to learn how to do it first.
Entrepreneurship is no exception. It's just that previously it's almost always been self-taught. There hasn't always been the availability of resources to help people learn the necessary skills like there is now. People learnt through failure; they tried something, failed, and got back up and did it again until they learnt what not to do. Those with the resilience to keep going became successful (which is still the case).
Fortunately, now there is a heap of great resources, programmes and channels to help people start companies much faster, and in ways that help to reduce risks of failure.
The block for most people when it comes to getting started is not a lack of information or support, it's not investing enough in developing themselves to the stage where they have the skills and mindset to build a successful company.
If you want to become good at starting and growing a business, then start learning the relevant skills and develop how you think. Read books, talk to those who have done it before, find relevant learning opportunities and get practising by making a start.
Continuous learning and self-development, by pushing yourself outside of your comfort zone is what entrepreneurship is all about.
You can take comfort in the fact that most people don't know what they're doing when they start out in business. And most people experience the discomfort that comes with not knowing, which might be what you're feeling now. The difference between those who become successful, and those who are still working away in a 9-5 job, is that successful people make a start and keep going, with the right support.
You can do this!
