Sometimes you just have to take that leap.
Here is a simple fact of life: words will turn into reality if you say it enough.
As a result: if we keep telling ourselves we are not ready, then we never will be. It doesn’t matter how much “preparation work” we are doing on the side, or how much we are learning before we make that crucial change in life.
If we say we are not ready, we needed to wait, and we are looking for that turning point, we will never be ready.
