Best advice for people who will launch soon?

To plan everything in advance and ask everyone in the team for support ;)

Great Product, Community, and Team support!

be prepared to avoid murphy's law: what can go wrong will go wrong

Many write that they have no boundaries with excitement, but my advice before the launch creates its own audience that will really wait.

Build in public and community support.

I'm launching soon, so I've been reading others' launch guides. It seems like the best advice is to find a handful of the best launch guides and see what resonates. In addition — something that I'm not sure is discussed enough — leveraging copywriting principles when crafting the name, description, comments, etc. is high-value.

Know your audience. Understand your target audience and their needs, preferences, and behaviors. This will help you effectively market your product/service to them.
