Entering captchas are not easy as you thought!

A few days ago,I heard about a new concept of making money online and that is by entering capcthas.You have to enter some images as shown in a textbox and need to enter them in order to get paid.I thought it will be really nice to earn by entering captchas and started doing it.I got a project where the minimum amount of captchas required to be entered per day was 1k and I thought it was an easy job to do.But,my hope was terribly shattered as I found it out that entering so much in a day is almost impossible.Some people make a group online and then only they can enter so many captchas per day.I understood my mistake and now I believe I should not any such captcha projects anymore.That will be beneficial to both the project provider (Me in this case) and the person who gives me the project.Everything is not for every one and we should always stick to things that we are capable of doing all the time.
