Great list! I have another to consider that I personally have 35+ years experience providing. Clean up litter outside commercial properties on foot using inexpensive hand tools. It’s almost as easy to do as going for a walk! I started doing this as a side gig in 1981 and soon grew it into a profitable full-time business. I share my experience in my book, Cleanlots.
Save money on food. I recently joined $5 Meal Plan in order to help me eat at home more and cut my food spending. It’s only $5 a month and you get meal plans sent straight to you along with the exact shopping list you need in order to create the meals. Each meal costs around $2 per person or less. This allows you to save time because you won’t have to meal plan anymore, and it will save you money as well!
