In these days, many used to learn and few used to earn online. This is one of the best source to keep in touch with worldwide folks and would get an opportunity to learn many unlimited things like multi-national cultural environment, multi-purpose, their lifestyle, their different interest, their knowledge sharing, worldwide historical, worldwide development and so on.
By using online tools, one can learn as much as he/she can without wasting time. Yes, me too doing the same as I am busy most of the time offline for different assignment but whenever I am free then I used to come online and learn a bit. There are few search tools that can give relevancy on interest of searching things. As such, we can be one of them who can give relevant information to the worldwide by writing known subject articles which could help anybody in the world.
The way we learn from offline and online, we can earn from offline and online too. How?, offline earning is normal on since many years or centuries that is happening worldwide in their nearest place but how about online earning? Yes, this too can possible as long as Internet is live since few decades and some of the online websites helps to share the knowledge or become blogging to share the knowledge for others' search thus one can earn reasonably.
Though there are many sources to earn from online like affiliate business, freelancer, writing for some website company, work for some website as moderator and show the ads on blog etc. but those sources can be used per individual talent to get the best benefit out of it.
Are you wasting time online? I suggest you not to do the same as long as you can fit for any one of the said online business and earn beside learning something out of the box. Try cost nothing, so, try it. All the best.
