Do you ever start your day with positive affirmations?
Science says that our minds don't really know fact from fiction which is why we cry in certain situations or when we see something that triggers us. Like the dinosaur movie 'The Land Before TIme' when Littlefoot's mother dies we know deep inside she's still alive but it makes us so emotional. So that's a trick for making affirmations work, say it like you mean it!
Basically you are creating an image in your mind of what you'd like to see in your life. For more confidence boosting affirmations see below and try saying them to yourself!
