Ok all snark aside - let's all agree that anyone asking how to make $100 in 3 days on this forum deserves some flack. You don't just wake up one morning and make that kind of money out of this air. You can make $1.000 / day but you don't start out making a $1.000 / day. You build up to it.
That being said, I do hope you weren't as desperate as you seemed when starting the topic. Believe in yourself, realise that you can do what others have done before you, work, persevere and thrive! Don't set a timeline, set a milestone.
Best of luck
