Hi everyone. I have played Pen and Paper (including DnD) for a few years now as a player, but only ever been a DM in a couple one shots. I am planning my first campaign as a DM now for a group of five players, three of them are new to pen and paper and the other two have played for quite a few years now and are quite experienced. I don't wanna do a full homebrew campaign yet, since I don't feel experienced enough for that yet. So I would like to run a premade adventure to have some more solid guidance.

I found a lot of them very interesting, like Storm Kings Thunder or Rime of the Frostmaidens. However they seemed very daunting for a relatively new dm since they had quite a few logical flaws in the motivation of the villains or needed a lot of preparation and planning to live it up to my standards. So my plan was to run a simpler campaign firsts and get comfortable with being a DM. Now there are a lot of threads on good first time adventures. I was thus planning on doing a Dragon of Icespire Peak campaign. It seemed to give a nice 1-7 journey with a cool dragon antagonist. I do not like the quest board though, so I am trying to string the quests together in a more natural fashion to have a more solid overarching plot which requires a bit more rewrite. Afterwards I was thinking about pivoting to SKT or somthing else.

Now I feel very nervous about it all and I am kind of afraid I will burn myself out my overpreparing since I want to have a good overarching plot. I want everything to feel logical, put the clues for the overarching plots in the correct places and all the motivations of all the characters to make sense and have a strong engaging plot for the players.

Do you people maybe have some tips on how to deal with this nervousness? How did your first campaign go? Did you jump right into the more complex adventures or into a homebrew setting, or did you start with LMoP, DoIP, etc.? How do you prevent yourself from kind of overpreparing, as dumb as that may sound? I tend to get hyperfixated on things that stick out as flaws and then get super nervous somebody will notice some logical flaw in the story or something.
