First like many have said. What do you wanna shoot, what do you like the most, which artist really does it for you ? If it's nature, how do you wanna shoot it, to who are you looking for when shooting, if it's street photography same, browse internet, read about it, go outside and shoot the hell out of your camera. If its portrait, same, start by asking your friends, do test shot, organise shooting, give them the photo in exchange of their time, also there's a lot of fb groups for amateur photog and model and mua, join them!
You might want to have a small agenda while shooting. Today I need to shoot at least (random)20 photos, I wanna have 2 diagonnal, one vertical, one horizontal, one leadin line, one clair obscure ... give yourself some challenge, make water the subject, make concrete the subject, have a model in movement ... Anything! Give yourself some goals.
Once you got enough photo, create a twitter, a facebook page, an instagram and even a website, ask one of your friend to compose a small bio about you if you feel uncomfortable talking about yourself. Set up a gmail,a contact form. Be present on social media like twitter and facebook, add models and fellow photographer, follow people, talk about them, share post and retweet, people will do the same with you
