Yes, there are plenty resources out there for you to continue to sharpen your toolset and learn from others in the community as well. Here are some of my favorites
1. Listening to podcasts - Women in Product Marketing by Mary Sheehan is by far my favorite. She brings on a host of Senior PMM's in their field to discuss topics from messaging, positioning, pricing, getting into PMM, GTM strategy etc.
2. Following thought leaders on Linkedin - Here is a nice list of thought leaders - https://www.productmarketingalliance.com/60-product-marketers-leading-the-way-in-2022/
3. Spend time on other websites - Some website I have come to love over time are Airtable, Asana, Snowflake, Zendesk, Gong, Drift, Dropbox, Evernote etc. Here's a good list of good B2B website examples and what makes them great as well
3. Spending time in the field with actual customers - listen to how they talk about their challenges, goals, aspirations and passions. What they like spending time doing and what they don't. Ask specific questions on how your product/service helps them, what they would do otherwise and take notes on the specific words and language they use to describe the value your product brings to them
4. Listen to Gong calls or shadow your sales/Customer success teams - to hear first hand on how your sellers sell your product/service, the slides and pitch decks they use, and their words and language. Pay attention to what resonates with customers, and what doesnt. Listen also, to how prospects describe their problems.
