Is 2015 the year you vow to stick to your budget? Does your budget keep failing despite what you believe to be your best efforts? Make sure you aren't engaging in these bad habits from About.com.
Is your budget practical? Or did you just create a set of numbers to follow that don't reflect your real life? You can't buy groceries for a family of four on $20 a month, even if you write down the numbers. Be realistic and set yourself up for success, not failure.
Make sure there's room for small rewards and splurges occasionally in your budget or you're going to wind up overspending and failing miserably. Even if it's just a tiny weekly indulgence like a Mocha or a small bouquet of flowers to brighten up your house, you'll do much better if you keep a little fun in your life.
An emergency fund is a must if you expect to be able to follow a budget. Otherwise, you will constantly find yourself over any time an unpleasant surprise pops up, from a dead car battery to a broken washing machine. Start saving now so you'll be prepared for the emergencies that always happen in life.
It seems obvious, but if you aren't really sticking to your budget, it's never going to work. Are you constantly justifying impulse purchases that don't fit into your budget? No matter how great your budget is, it will never get you where you want to go if you don't stay within its guidelines.
