You can start looking for inspiration from your lifestyle, which is about recording what you are doing or some landscape near to you. By editing your first short video, you might got more idea for writing script and direction what you really want.
As you want to learn more about writing, you can read some more books as a reference, it will improve your writing skills and get some ideas to unlock your creativity. For learning about video editing, you can start from easy softwares, for example, like iMovie, FinalCut Pro, Adobe Premiere, Lightroom, Photoshop etc.
Glad to hear that you interested in filling making, if you wanting to extend your career in film, my suggestion is to find a film school to learn more about the professional skills or film-making knowledge.
During college, you could also find some internship programs related to video/film making, India got the famous 'Bollywood' films therefore you could be inspired by that, by exploring different type of videos or films from all the resources, then you could find your own style of making films.
This is my opinion, I hope this will help you to achieve your goal! Just do it and start practicing from now on! :)
