What makes you believe in your craft?

As the title says, I some insight. I'm a begginer witch, a part of me wants to believe with all my heart that I'm strong and powerful and there is magic in the world. But there always comes the "rational" mind that tells me all of this is bullshit and I'm silly for believing. I struggle with this because I have no one around that believis in the craft, and if I'll tell anyone about the path I want to take they'll call me stupid and childish for it, make me doubt even more. Can you share some experience with the craft to help my stubborn mind? I have some experiences but my mind still finds logical ways to make it not magical and just coincidences.
