Well, I'm still learning, it's just my 5th day working with instagram. Not looking to make money right now, will start monetizing around 3-4 months later, if not more. Depends on how fast I get enough followers and what's the engagement rate.
I'd suggest the same to you, don't look for "100$ a day method that u can master in 5mins, noob friendly and fool proof", these are too good to b true. The only actual methods that work like that are scams. And you don't wanna scam to make a living, coz some day, that scam will get busted and u wont have anything left.
Start slowly, hands on approach is the best way to learn. When I started with instagram, I didn't even know how to follow people or how to upload content or where to get content. Been less than 5 days and I'm doing everything perfectly, now I'm learning how to unfollow and whats the right number. If I think too much before taking action, I won't be able to take action.
So take action, start something with basic knowledge and then learn with time. You might fail a couple of times, but failures are the pillars of success. You didn't fail for nothing, with each failure u learn how "not to proceed" and u can try something else the next time
