It's no joke. Your words are powerful!
Speaking things into existence, of course, is not really magic (even though it really feels like it). We just need to declare the things we want to happen.
By saying these things out loud, not only are you making a mental note to do what you’ve said, but you are also informing another person of what you want. Once you have shared something like this, the person you've told will probably ask or remind you about it, meaning that you will always have that outside voice advising you toward it, as well as yourself.
Speak about your future with hopefulness, enthusiasm, and knowing!
