All in, baby
Our spirits, souls, and bodies, love thrive when we are “all in”.
To be all in means believing in yourself and everything you commit to 100 percent. On all the levels mentioned above, we can sense when we doubt ourselves or the other person or thing. The results of that doubt can be detrimental, either leading to self-sabotage or "other-sabotage" at a gross or subtle level.
Being all in can feel frightening as it takes away your escape hatch. However, giving yourself over entirely to your worthiness and a big possibility is the only way to fully know yourself.
If you cannot believe in the other person or thing, your work is either to choose to believe or realize it's time to find what you believe in. And to discover that thing, you must believe in yourself. It all starts there.
