Build what makes the next person’s first step better.

The hardest part of most things is the beginning, when nothing is familiar and you cannot tell which difficulties are real. Improving that first step for someone else, with a clear starting point or a worked example, removes a disproportionate amount of the total difficulty.

Remember what confused you at the very start of something you now know well. Write that down for whoever is arriving. Beginnings are where help is cheapest to give and most valuable to receive.
