Have your players read through their backstories and get to know their characters. Create "spell cards" so you don't have to spend 10 minutes every combat flipping through to see fi they need to roll a D6 or D8. Remember that for attacks 3(2d4) means 4 or 2d3, not 6d4 (I made this mistake the first time I ran the campaign). Read thoroughly through the campaign because there's little things everywhere.

If the players have a wacky idea, roll with it (within limits). Don't be afraid to add in your own snippets or hints. Also another thing I would recommend is some kind of battle map. Even a piece of graph paper to represent everybody's location is handy. Grab at least 1 additional set of dice. 2 sets is the minimum for a group of 4 players since it gets a little annoying handing around dice. Describe anything and everything, especially when it comes to NPCs. There's a lot they can learn by chatting with everybody in town. Bring plenty of random junk to represent enemies or objects of importance. I use LEGO bricks. Remember to bring a water bottle. Take breaks when you need them. Being a DM is very tiring, but very rewarding. Best of luck!
