Welcome Muskandhigra, with this aditude I don't have any doubt you're up for the fine journey. I think you made a first and most important step, and that is - making a promise publicly. You will keep yourself accountable from now on, and these two people in comment section will as well.
Second - find yourself a tribe. Group or multiple group of people who read and honestly engage on work of other writers. They will support and keep you motivated on daily basis. Reciprocity. It will help you grow.
Third - join medium groups on facebook, just type in medium group and you'll find plenty. By first couple of post you'll see how the group breathes, blend in and share your work
Third - write valuable content. I already have a sense you know how to do that.
Fourth - follow people. Engage with people. Pick the ones who are growing as much as you are. You will find some wonderful writers.
Five - enjoy it, have some patience, and aim on the long run. Medium is not a perfect platform and it won't bring results fast. But that's a whole different story 😊.
Good luck to you and wish you a happy 2022
