It’s not complicated. And, yes, you are doing it correctly.
You can release your questioning. When you listen to your heart, you are doing it – whatever “it” is (your job, your relationship, your spiritual practice) – correctly. If it feels right, it is right. If it doesn’t feel right, you know it.
Your effort, your willingness, your passion, your authenticity, is bringing you success. It is. Believe it.
