I found Your Money or Your Life to be a great guide for budgeting. Briefly:
1. Keep track of every cent that comes into or goes out of your life.
2. At the end of one month of doing this, you’ll have enough information to group your earning and spending into categories (make them as custom and specific as you like)
3. For every category and amount, ask yourself if your spending is aligned with your values and priorities, and whether you feel satisfied with the spending (i.e. whether the expenditure was really worth it).
4. Repeat.
There’s more to it, obviously, but when I was living this, I took home $1,000 a month. In a few months, I had $1,000 in the bank. Not long after that, I bought a motorcycle for $550 and a car for $600. All the while I maintained about $1,000 in the bank. What I didn’t do was see a movie in a movie theater for about 10 months.
