I was just thinking about this the other day and making money online is definitely harder then making a buck online,but those who make money online have some key advantages over those offline.Those who want to earn online,learn early on that to make money,you have to invest a lot of time and sweat to make something,this way they learn the importance of endurance and believing in yourself.After you have made a name for yourself things get better and you can focus on working and improving your skills.Whats important to say about online work is that even thought its harder to make money in the start,later it just gets better,I didnt say easier,you get out as much as you put into it but I think of it this way
"Making $1 offline is easier"
"Making $10 offline is easier"
"Making $1000 offline is easier"
"Making $10000 online is easier"
What I am trying to say is,that after you establish a business online,and you found a strategy that works,it all depends on your allocation of resources and the effort you put into your business,if you worked 3 hours/day and made $3000,if you work 10 hours/day and there is enough work of course,you could make $10000.
