There seems to be a misconception that you have to be proficient in everything you do. Sure, it would make things much easier. But to set the bar so high for yourself for everything you do and will ever do is to inhibit the opportunity to learn as you set yourself up for discouragement.
Want to become a great writer? Consume content and write every day. Want to become proficient in playing guitar? Commit yourself to practicing. Want to become better at your job? Read the manual, talk to your boss about areas of improvement and apply the criticism.
When you decide to do something, commit to it. Even if it’s difficult at first. It can only get easier and easier from there.
