One day I was playing around and acting like I could control the water. The water started moving slightly but at the same time I felt a breeze but thought I could still control water. The next day I tried controlling earth and a tree moved and again there was a stronger breeze. A few minutes later I tried playing with wind and a bunch of mulch flew at me. It was that moment I found out I could control the wind.
I went to a park the next few weeks later and tried playing with the wind again and some sand started moving in the direction of the wind. I told my friend but he didn't believe me so I hid behind the closest building by the park a played with the wind then he threw a plastic bag and I moved it a little then I made a stronger wind and blew it to where I couldn't see it. The next day I ran outside and caught up with my friend who was riding his bike and picking up all the papers he dropped for his play. I tried to help him but he just elbowed me in the side so I backed up and made a wind come that blew his papers further and he turned back and some how blew a wind back at me. He told me he could do the same thing and I nearly blew myself off of my feet with a wind. My friend moved away the next month and now I'm stuck with these "powers" with no friends with the same "powers" to practice using them with. But I still so often move the wind a bit when I'm either excited, upset or angry.
Wind is tricky. Once, I got a stream of water in mid-air, but... That's about it.
Try using other elements.
Don't show anyone. Please, don't.
