A good goal when first starting out is to always have at least $200 in your checking account and $500 in savings.
As you increase the amount of money you make raise the amounts in your accounts. Challenge yourself like it’s a game to see how much you can have in there at one time.
Think of money in small amounts, for example every check you get pull out $25 or $50 and throw it into your savings. Pick up pennies that you find in parking lots and put them in a jar (this is my favorite thing to do). You can accumulate a lot of money quickly by collecting change. A lot of banks have machines that will count the change for you and deposit it automatically into your account.
