I prefer credit card for payment, but I always end spending more. Is there any solution?

1. Reduce your credit limit on your card to level just above your monthly budget.
2.Use a different card for diferent spending, for example one for petrol, another for groceries ( set limits as per 1. above)
3.Keep a tab on your spending & what you have left.
4. Never buy anything on impulse with your credit card, use cash.
5. Go through your card bills, see what was needed rather than wanted! Then pay them in full, (set this up with an automatic payment with your bank).
6. Keep away from those places of consumer temptation.
7. Keep one card for emergencies, such as car, house repairs ect.

All this should help you treat your credit card as a debit card & promote fiscal discipline, yet retain the flexibility of your plastic pal who's fun to be with!
