People lie to themselves every day. They say need vs want and say investment vs expense.
Listen to yourself as you talk about how you spend money. Thoughts become actions. Actions become things. Thoughts become things.
Just like when you cannot accomplish things in an environment of lies. You also can't accomplish anything financially when you're constantly lying to yourself.
"I really need a new dress for tonight."
"I'm starving right now! I need food!"
"I'm going to invest in a new phone."
