Do you have any tips for planning a one shot as a first time DM?

dnd-inspiration:

1. If you want your players to meet a certain person, or run into an encounter but they’re going the wrong direction, just move your encounter/person to a new location they’re moving to. I do this all the time and they’ll never know.
2. Don’t give them a giant map with tons of places drawn on it for fun. They’ll immediately ignore whatever hook/quest you gave them and run off.
3. Keep little notes about towns/important people and keep them by your DM screen. “Littlerock: Export rocks, town of rock golems, peaceful. has inn and bar”.
4. Don’t plan an encounter where they lose if you want them captured for story reasons. If you’re just starting out, just tell them they’ve been captured. Ask them how and why they were captured, and give them a chance to break out with their stuff. Or pay a fine.
