1)First you have to see what is your basic needs.which is food ,water,electricity,clothes and so on.
2)Second we have to check our bills if it is over the limits and how to reduce it.
For example : our electricity bills is it over the limits or it is good.sometimes people leave lights on in all the rooms even if they are not using it,same for other electric things.
3)When we buy food we should buy our needs not extra and next day or after few days threw it.
4) We can buy our clothes with good prices.
We should do a list with all our needs and then check what is important and what is not,then save the extra.
