In week 3, my levturer Dr Syamsul show us one video. that video is about bicycle. What is interesting in that video is that is not a normal bicycle but it is a unique. in that video showed tahat one guys have design and transform a normal bicycle to to the contrary. he took a few month to train him self for riding a bike in a way that error. he also train his son and his son just took a few week to riding that bike. this can prove that children more easy learn something the thing compared with adults. What I can conclude with watching that video is, no matter how difficult we want to get something that, we just have to be patient and continue to work until we get what we want. By watching this video , I also learn a new thing that we as a person need to try a new thing that we dosent have do it.
