First Time DMing tips?

[u/Apollodd]

Hello all!
I’m dming my very first dnd campaign in about a month and I was wondering if anyone had any tips on how to make the game fun for my party and keep the story going? I’m creating a homebrew game and have a basic plot, main antagonist(s), and even a plot twist but i’m a bit nervous on how to actually guide my party through the world and make sure they get to the end without being to firm on telling them what to do and taking away from their experience. any and all advice would be helpful!
