I am hoping to maximize more income in the future through cutting costs. Here are a few things I have done:

By taking cold showers and not using shampoo as often within the past 2 months, I have been able to save a good bit on my water bill and some necessities like shampoo. I am also trying to take advantage of places like coffee shops and libraries to do some work on computer to avoid being charged at home for electricity. What are some other suggestions you have on saving utilities?

I can cook myself breakfast foods, so i have been able to save myself a little bit more for groceries. However, I know there are ways to meal prep for several days that is time effective and cost effective. I want to eat out less. What are some suggestions do you guys have for meal planning and prepping? I have no idea where to start for lunches and dinners.

Besides the above topics, what are other time-saving and cost-saving methods you guys have looked into?
