Took me a little bit more than 2 years, but I do not believe in time so I do not consider it a lot 
. I believe the later you start the more time might take, especially if you have no idea what you are doing. I was basically more of a blogger, my first year and a half before I was pointed in right direction.
I believe the key is not how long it took you or it will take you if you just starting, but to be fun for you and so you can stick with it even if it takes 25 years. So I guess u have to be a little stubborn, or a lot. If anyone new is reading, I hope this encourages you to continue, as not everyone started making money on their first month.
