Why do I do what I do?

I have wondered about why and how I have made decisions about what I want to do. I must admit I went through a pretty scary phase in my life where I was gripped by fear and I was not able to let go of my lucrative corporate software career. I am quite happy I did as I feel so connected to my higher purpose and why I came on this planet. I used to have questions about why I am here on this earth but as most people do, I made myself too busy taking care of basic needs so I wouldn't have to tackle these tough questions.
