To help you, the important thing is:

1. Get to know yourself. If you know you can't go to the mall that will spend more than you think, don't go to the mall.

2. Have better control of your savings, the basics such as: - how much you spend monthly and how much you receive monthly. I always recommend this application here to help you with spending in detail. mauriciojunior.net/app/36/financas-academy

3. Involve your family in spending and earnings, so they will know and understand that sometimes "spending" is not an option.

4. Celebrate the victories, especially with the goals. Stipulate a goal, when you reach the goal, celebrate to show you that it's worth it. It's like training with your pet, if he does what was proposed, he gets a snack. Do the same with you and your family.

Never stop studying about finance.
