For me there are lots of Easy method to manage money.  Using a small notebook to track your spending. List all must pay bills such as rent, utilities, car payments, insurance, food and transportation costs(gas) Then everyday of the month write down every penny spent.
At the end of the month look at what you wrote and see where you can cut costs or not spend. Total it up. Minus the total from your monthly income. Using the balance What would be the maximum you could bank? If it is $35.00 then the first of the month make a check for $35 and put in savings. This is known as paying yourself first. It really works. So good luck
