Based on my experience so far, there's one thing I can work on that will have an immediate impact on the business.
Being a better writer.
I've found that if I'm not in a meeting or pitching someone on our startup, I'm writing. I spend my time writing content for our website, writing warm/cold emails, or writing blog posts.
Becoming a better writer will mean I can get my point across more clearly. I'll be able to relay our value proposition to potential customers, convince businesses to work with us, or even build a community of supporters. Writing is integral.
Yes, I'm working on other things like how to talk to customers (see The Mom Test and Talking to Humans). But I won't be able to talk to anyone until I can actually get their attention first. If you have any great writing tools or suggestions, please let me know!
Writing will lead to conversions–whatever they may be.

I had the same issue. I pay writer between 2-3 cents per word, it frees me up to focus on the business instead
Interesting! Thanks for sharing the idea.
