I have been Hindu for four or five years now. I don't remember exactly as I'm not very good with remembering time. I had been studying all the world's religions for years and then in high school, a Hindu girl wrote an article on Hinduism in the school newspaper and that set me on the path. It wasn't until a few years later that I contacted the local temple and asked what I had to do to become Hindu. The priest was very welcoming and I have been Hindu ever since.
I go to the temple weekly and on festivals. I do puja at home every day. It's pretty simple, but it's something. My Ishta Devata is Lord Ganesha. I study scriptures every day as well, such as the Bhagavad Gita, and condensed versions of the Puranas, Ramayana and Mahabharata. Eventually I'm going to pick up some copies of the Vedic Samhitas and some of the Upanishads.
If you have any questions, please feel free to ask!
