★ Essential spending is things like rent, bills, debt: stuff you don’t have a choice in spending money
on. You can also split essential spending further into fixed (costs that don't change, such as rent) and
variable (costs that do change, such as food).
★ Non-essential are things you could do without: takeaways, online shopping. Depending on your goal, you
might want to see if you cut down on a few of these.
