'' A person who never made a mistake never tried anything new ''

Albert Einstein 

About several days ago , i lost my mobile phone ,at that time i went to gramedia metropolitan mall by any self..

   

  As always for the firs time ,i need to take my time for player dzuhur in the ground floor.Then i go directly to book store,without checked my stuff ,i don't even know that i left my mobile phone there .

        In the bookstore i checked my bag ,i found nothing ,there was no mobile phone in my bag , i have lost it ,it must be left when i prayed ,i tried go to back to mosquito and asked everyone but no one knew was no mobile phone there. I called my number but it did not active any more .

what does it mean ? 

 after i lost my mobile phone and i found nothing 

,i really shoked ,regret and sad ,because i never expected it will happend to me.

why is it important to learn from the mistake ?

i have learned that i have to be more carefully for the next time 

and i have always felt that stuff which we have is precious .
