Experience costs us misery, time, trials and errors. Experience is not that easy to gain. For instance, if you buy something from the market for the first time and you don’t know the right shop to buy it. On bringing that thing home and after using that thing you find that that thing is non genuine, you will be in loss. Now you will go to other shops and for the second time you will know some difference between genuine and non genuine. On the second or third time you will definitely know the difference between the right and wrong thing. Now you have gained experience but on the cost of previous two non genuine things.
