Between the family, the monthly payments of the house, the daily purchases, paying the tickets to our workplace, many times the money we earn is not enough to pay all our debts on time, but we have many alternatives to achieve it.
One of them is to earn money on weekends, and it is not about taking a second job as such, but about creating an activity that becomes a family tradition to help with household expenses, such as baking cakes to sell. All children love baking cookies and spending time with their parents.
You can even teach them how to earn their own money by having them sell their cakes they make at school, which will show them that they can make money honestly and easily on their own.
Obviously at the beginning you will not earn as much money as in your main job, but you will be able to pay all those ant expenses that do not allow you to pay your debts and save.
