Make a plan
Make a budget
You can't get very far if you don't know where you're going, so make a plan.
I'm not calling it a budget, but you certainly can if you want to.
Grab pen and paper, your phone's notes app, whatever.

1
Track what's going out
Keep record of everything you spend money on for a week, two weeks, or one month. A month is best because most, if not all, of your income and your bills will be included. How you do it is up to you. One option is to keep every receipt in an envelope (making sure to jot down what it's for if there isn't enough detail printed on it... hello shopping amnesia!) Or use an app like Mint or your bank/credit card transactions log. Or keep a spending journal in a notes app or in an old fashioned notebook. Whatever works for you.
Don't forget to make note of seasonal spending and periodic bills that may be due every few months or even once a year.

See what's coming in
Paychecks, benefits, gifts. List all the ways your wallet and bank account may grow over the course of a month.

Look it all over

Now for the math
Income
- Savings goals
- Spending on needs (including debt)
- Spending on wants
_____________________
= 0
Start with your income, and subtract budgeted goal spending, then needs and wants. The end result needs to be zero. Zero? Yes, give every dollar a job. If you have leftovers, increase your savings and maybe even plan for a splurge if you can afford it. If you come out with a negative number, take another look at your spending on wants. (Or even your needs... you may be able to trim there as well.) If that doesn't work, look to increase your income.

Put it into practice
You now know what you have to work with. If seeing it laid out like this works for you, go forth and make a plan. Many people like to use online/app software. I've used Mint before and am currently trying YNAB ("you need a budget.") If a piece of paper on the fridge works best for you, that's cool, too.
