I have been looking at my library of books about personal finance, I find it overwhelming and I do not have adult ADHD. You can have any rules that you want when it comes to managing finances as long it cover a few core areas.
1. Education - There are so many people who are looking to take advantage of the under-informed. Education is key in figuring out what you want and more importantly why you want it
2. General Philosophy- Do you like to play it safe, or are you a risk taker? Are you a saver or a spender? How much do you give to others? There are no right answers to these questions, but you need to know yourphilosophy on money, so you can understand and defend to yourself your financial decisions.
3. Goals - One you have established your philosophy, its important to set some goals that are in line with your money management philosophy
4. Systems - It is important to have a game plan with managing daily spending, paying bills, and making day to day decisions.
5.Analysis - Are your goals, systems, and philosophy working for you. What are you doing well and where do you need to change.
