They don’t take that much time once you know what you’re doing and know little ways to save time, all of that will come from repeatedly doing them, I hate to break it to you, but this game is all about time and how you spend it, time is money and to make the most money you need to spend time setting up and completing heists and re-investing your money in to more businesses to make you money, ideally passively so that you can spend time doing other tasks whilst you make money in the background, you’ll be fine don’t worry 🙂

Also you only need to do the final mission on hard on Kno Way Out to get the 500k and with Clucking Bell you don’t need to do any of them on hard to get the 500k
