Wisdom of Money imparts a very important message not just on spending but on investing habits, quoting them verbatim...
Wisdom of Money: The Way You Think Dictates Your Spending Habits
Prosperity thinking can be defined as a trusting attitude that things will work out. It is an optimistic state of mind, and an empowered orientation toward money. Prosperity thinking means aligning our beliefs, attitudes, expectations, goals and behaviors toward realistic levels of abundance, confidence and gain. It increases financial and personal self-esteem and assists in using our feelings and intuition to deal with money more successfully.
Poverty thinking, on the other hand, is a mistrustful state of mind that says things will not work out. It embodies pessimism, fear, and a passive relationship with money. A poverty thinker aligns beliefs, attitudes, expectations, goals and behaviors toward unrealistic levels of scarcity, fear, and loss. It diminishes our financial and personal self-esteem and decreases confidence in handling money. Such messages can cause us to distort how we perceive an event and explain why we react irrationally. Almost everyone, including highly wealthy people, is a victim of poverty thinking to a certain degree.
Prosperity and poverty thinking are two important concepts for understanding the psychology of money. Studying various spending personalities and behavioral patterns provide us with an awareness for making smarter financial decisions of our own. Because the mind takes precedence over our actions, to think and feel more prosperous creates new opportunities for experiencing financial freedom.
