the singular best tip you have?

Just wanted to hear from you all about what you wish you had known from the very start, or the most useful piece of info you’ve found. However big or small. I learn well with quick tips that I can incorporate as I work, and you are all such inspiring artists!! I know there’s no quick way to learn, but just hoping for the most important tidbits you’ve learned along the way. Appreciate you all so much!! ❤️
