You want to read!! That itself is an amazing starting point. Beyond that, though, you're right, it can be pretty hard.
The first step is to figure out what you're interested in. This will take some experimentation, but if you try to force yourself to read when you're really not interested, it'll feel like a chore, any motivation you had will disappear, and you'll be worse off than when you started. So start looking into different genres and find out what works for you. If you like movies of a certain genre, you can start from there. If you have friends who like to read, you can also ask them for recommendations, because they know you and might know what you'd like.
Always sticking to one type of book might get boring, too, so don't be afraid to spice things up! You might discover something else you love.
If you do have friends who like to read, and they recommend books to you, they'll probably ask you about your progress lol so you'll have a reason to keep reading. Take it from someone who reads and has a lot of friends who do as well-- they will NOT let you forget. You could also ask them, or your family to remind you about your reading goals!
This next part is important-- don't feel like you have to read. It's great to have a schedule and to try to sit down and read every day at a given time, but if you try to force things... like I mentioned earlier, you'll lose interest. There's no rulebook that defines what a reader is. If you read one book a week, you're obviously a reader. But if you read one book in a month, you're still a reader. One in a year? You're still a reader. Your speed and the amount you read don't change how much of a reader you are, so don't put too much pressure on yourself. Just have fun!
Oh, and! One last thing. If you find what you really like, and they're books "meant for kids," or just not "cool enough," don't worry about it. Read what you want, your reading journey is your own. Other people's judgements mean nothing.
The tips from the other answer are also useful! Hope I could help you!! (GOOD LUCK!!)
