One of the biggest things you can do is track your spending. Each month, write down all the things you may spend money on, and keep track of it on a spreadsheet or a notebook. If you have a calculation for how you are spending money, you will know how you spend your money.
You will then create a budget. Make a 5-year plan followed by goals that are done weekly, monthly, and yearly to see the progress of your 5-year plan. Cutting spending will be paramount for this to occur.
