Really though...
I used to recall whatever I remembered by heart or other already learnt concepts whenever my mother asked me to bring something from the market or from the nearby shop. This was my routine since I was in the 10th grade. This not only helped increase my productivity, manage my time for the repeatation and but also complete the house chores I was assigned to at the same time.
Utilizing the time this way wasn't my idea though. One of my neighbor friend, one year senior in studies, shared his this strategy with me. Later, he completed his Ph.D in Applied Mathematics from one of the U.S. universities.
I don't know if this exercise was the reason or something else. There were two incidents when I forgot the names of my friends while visiting their homes. First incident was when I just joined in B.Sc. and started to get understaning with one of my classfellow which later turned into friendship. When I visisted his home for the first timne I forgot his name. My brain was just a blank slate for almost two minutes - real embarassing. He used to live in a three story building, a kind of combined family arrangment, three brothers and their families, each on a floor of the smae building. When I rang the door bell (I rang the bell of the second floor) his uncle opened the window on the second floor and asked me who to call. Suddenly, I was speechless, my brain was completely blank. This condition existed for almost two minutes. This remained a joke to discuss for my friend on several occasions for many years to come. I felt real embarassed every time. Second time was almost the same.
Interestingly, I remember the construction of the concrete roof over the ground floor of my grandfather's house when I was only 8 months old. At the time, they used to use wooden shuttering for the construction. You must be thinking I am over stating my age. Let me tell why this is true. That day my father come out of his room, me being on his lap, and reached at the portion where the roof was constructed I looked up and a cold water drop hit my forhead. That cold water drop froze that scene in my memory, I would never forget those visuals. Here, the cold water isn't the trigger for me to remember that memory but it was the catalyst that will keep that memory alive as long as I live. There are some other incidents when cold water rain made some memories live as long as I am alive.
It is funny, most of my favorite songs today are those I used to hate during my childhood.
My parents used to listen their favorite songs of the time or old songs (for them, for me they are ancient). My father listened to them at the breakfast before going to work and my mother listened while doing house chores. This was during late 70s and early years of 80s. God, how I hated those songs, that music was just too much for me. This was continued when I was 13 years old. My father died and mother stopped listening them. It was 10 years after that when I was going to the university by bus. I had missed university bus (We used to call the university bus "point") and was using private bus for the transport. The driver started playing some songs on the audio player (This wasn't illegal at the time or may drivers didn't care much, all of them play music). These songs were old and most of them were what my parents used to listen and for my surprise I was enjoying them.
Later, during the years, after asking my mother hers and my father's favorite songs I litened to them all and some and they became my favorite.
(I am using scrobble.life/music to list and to know approximate numbers of all of my favorite songs. This is an interesting site developed by acidyo. If you haven't use it then I suggest to do it. It also has many interesting games as well and is constantly being developed and getting more features.)
What I haven't shared or discussed here is how I learnt to manage my memory but, I think, that is not something to discuss under reflection so let leave it there.
