That's a good way, in short, your lifestyle should not come along with your income... Everytime you have extra income or your salary increase, try to be the same, that way you will see your income increasing and at the same time you could control your self from spending unnecessarily ...
No matter how rich you are. If you start putting a lock on your expenses, you will earn money. I may sounds weird but it is the truth. Cost efficiency living is a gurantee for succes.
Yes very true but i think to earn you must need a proper disciple to yourself and try not to look for beauiful things and buy it when it is not usable for you. Other there is avoid to gamble to much money because high chance to you lose big money and you left nothing with it Just focus to discipline yourself and thats the key to save.
Discipline is the key for success for sure, if you don't have discipline in you and if you lack control on your spending then you won't be able to save single penny.
