Mental freedom is the product of mastery in several areas of our lives. We must master ourselves, our relationships, and our money. Mastering one without the others (or some without one) will leave us subject to an undue external influence in the area(s) that remain which will keep us bound. Freedom isn't free, it takes a lot of hard work.
Convince yourself everyday that you are worthy of a good life. Let go of stress, breathe. Stay positive, all is well.
Your mind constantly seeks proof that will confirm your beliefs. If you have negative beliefs, your mind will seek to prove those negative thoughts. If you have positive beliefs, your minds will seek to prove those positive thoughts. Therefore, it is important to be mindful of our beliefs.
