Online work might not be good for your friend, but if it's genuinely something that you find interesting, and if you are willing to put in the work it takes, you CAN make a good living by working online. And a great thing about working online is that there are so many different avenues of income opportunity.
Now, I'm not sure exactly what kind of training you have invested in, so I can't recommend which avenue is right for you, but I can promise you that no matter what, a monetary investment in yourself is ALWAYS worth it. Even if you don't succeed in that particular area, you've taught yourself SOMETHING, even if that something is that it just isn't right for you. Educating yourself is never a waste.
Besides, how can you beat laying in bed in your pajamas all day, controlling your own schedule, and making your own decisions on HOW MUCH money you make??! You can't. I have a hard time seeing how anyone doesn't want to work from home online! :think: lol Seriously, it's worth trying for sure if it interests you. Once you get the hang of whatever you're wanting to do, it just keeps getting easier and easier to earn more and more.
Good luck to you!
