It is really hard to control expenses specially when it is already your hobby. Spending is just easy to do. You can spend billion a day for anything or any expenses. Maybe a need or a want. Indeed, you will end up wondering; just like dreaming of the hard-earned money you have worked for years which you have spent in just a day.

Spending could be our daily routine. Might use credit card for groceries, stuffs for personal necessities or needs or the like makes us spend. Even if the actual stuff that you are currently using is just a plain card not the actual money, it still clicks on your debt. Uncontrolled spending could be the cause why there is debt. 

If you are able to separate needs from wants, you'll know what is necessary and not. Needs are those things that are essential for our daily living. Like food, shelter, water and clothings. We can't live in an absence of those things. But your wants are different stuffs. They are those things you don't really need at all, or just some sort of beautification stuffs, or enhancements or just a fruit of your imagination.  For example someone says "I need water but I want the flavored one". Well from that example, we can say that need is really different from want. You can have the natural water, but you opt to choose for the flavored one which cost you more.  

Spending what is really necessary is the first thing towards controlling your spending. And when you control spending, you start to save something and specially you're preventing debt growth.  Debt is just the fruit of uncontrolled expenses. Being responsible enough can start with managing your daily expenses or budgeting. Think that your income is just sufficient for your daily need, don't  spend more than your budget, it will just lead you to debt.

Start to manage your debt now. Pay it on time to prevent interest, and take control on spending. And sooner you'll feel comfortable enough if you don't have things to worry about specially debts.
