If you're wondering where to begin, start with what you already have.
Three short lines are enough:
1. Time I can set aside for learning: ___
2. A skill or experience I can bring: ___
3. One question I'd like answered: ___
Your learning time could be 15 minutes. Your skill could be organizing, helping customers, or explaining things clearly. Your question can be as basic as, "What is an email list?"
This gives you a starting point that fits your life right now.
Write your three-line starting point in the comments.
