Hi @scouts2222 - Since you're new, I just want to be sure that you know that you can use the pause button to create a queue of things you want your sims to do, and also use the arrows or number keys to make the time move faster or slower. (normal speed is 1, fast speed is 2, ultra speed is 3). Apologies if you already knew this. Depending on what you're trying to do, there are many ways to either speed up how fast your sims do some things or have them do two things at once to get things done faster. If you have questions on getting something specific to work faster for you, you could start a new topic and ask for some suggestions. You might get some useful info from this post: https://answers.ea.com/t5/General-Discussion-Feedback/how-to-slow-down-time-on-sims-4/m-p/8625236#M20979
If you decide that a mod is the best way to accomplish what you want to do, please be aware that you do have to manage mods. Whenever the game is patched, you'll want to check with the mod creators on whether the mod needs to be updated. If you experience any bugs, you'll need to know how to remove the mod and check in a new game to make sure it's a bug with the game and not with the mods. Mods can add a lot of functionality and fun, just be aware that you are responsible for keeping them current in your game.
Happy simming!
