How to be a composer?

Hello beautiful souls, firstly I want to tell you I love listening to music. When I listen to a piece of music, I wonder what the inspiration of the composer behind it is. I want to know if all this talent is god gifted or we make it with practice. I want to pursue music composition as my new hobby, can you please guide me through how I can start?  It’s not like that I know nothing about music as I used to play guitar and piano in my college days but I’m not remember that much now and yes please consider me as a complete beginner.

Thank you. 

Just begin composing. Don't wait to "feel ready" 🙂

You can start for free using Musescore and read scores (highly recomended) on imslp a long with youtube for audio.

Start learning how to read scores with some basic music theory. find a teacher or teach your self. 
Then post the scores here on the forum for feedback.
That a lone can take you far with some patience. 

Just focus on small improvements constantly every day!

Good luck! 🙂
