Crazy Human beings !!

If "future" can only be created from "past" then what's the role of "present" ;-)  but then how  many of us are actually able to live in present.. Your mind takes you to your past and to your future. 

Human beings want change and at the same time do not want to get disturbed from statue quo 

Look at the funny situation...Human beings pay money to save time (All automation so far ) and then they pay money to do something with their free time (Travel,TV,Books,Holidays,Gyms,Hobby Classes).

They spent money & time  to learn and then realize that learning has become their bottleneck as well.The only way out is to unlearn and learn something else to avoid this or at least get an illusion of same.

So business houses or marketers make money from their 

• Time -Help them save time or consume time & this fight is unending....Technology helps you save time and also helps you kill time. 
• Knowledge/skill  - Or lack of same , believe me many lives will not be enough to learn everything which human mind has created in  thousands of years so do not worry you will always have something to learn
• Experience - You do not buy a product or a service for the sake of it but for a underlying experience which comes with it after it's usage/consumption .Key is EXPERIENCE that too by your EGO mostly as body has very limited needs ;-) and the more you satisfy your EGO the more it grows at your cost.. This experience you get can be of joy,pride,happiness,peace etc.

Human beings have invented currency instead of barter system as barter system  would have been sufficient for human need but for sure not for human greed. Barter System has it's limitation .Under barter system ,scarce things become expensive like gold,diamond not because they have a better use but because it was was satisfying human greed under barter system..Accumulate more gold and more diamonds..but after currency system ,it has even become easier..Now you can have trillions of dollars without having any thing... & you can make people work for life to get those .There are no more slaves but people are still slave of their mind and ego..)

Good marketers are smart (or cunning,depends you are on which side) enough to  see the hidden needs (& greed ) of human beings and create new services/products (We call it value addition ;-)) 

Everything has two sides..to it.or I will say many sides to it.....It depends how you see it.
