making extra money is not so easy

I disagree. I do think it is possible to achieve big things online as well, but you need to be hard working, patient and not give up in the first place. You also need to be able to learn new things and have good ideas. If you don't, you will not be able to make big bucks online. But that does not mean it is not possible for those who do fit the above criteria!

I have same thoughts with you. I see there income too low compared to what we spend. But I'm still involved because what I want is your English ability will improve

yes if we dont get the right site to earn..it would just wasting electricity,time,internet.but if we gt the right site who pay good then their we cant call it wastage but a help to pay electricity bills(hahaha)

well without pain there is no gain and so you can't earn money for free. making money online requires skill and patience and also my lot is not wastage of time until you categorize and do work under by assigning them priorities. well using this site you are interacting with others, get a nerve of others opinion and views and you are earning money while learning and interacting so if you have to earn big you have to do a swot analysis of your own and have to put all your energy in the best. best of luck for your future

sure it is you are absolutely right.It leads to wastage of every resource we have been using in our daily lives.
