Does Human Uses only 10% of their brain power?

The 10% statement may have been started with a misquote of Albert Einstein or the misinterpretation of the work of Pierre Flourens in the 1800s. <-
From the very second I read this quote , I was really curious that if human really uses only 10% of their brain and I really wanted to test it myself , I dont really want to depend on the quote of what other people write if this is fake or real , I just want to believe what I saw, hear and feel . So, do we use just 10% of our brain and die out just by using 10% of our brain? If thats true I would really want to change something about myself before I die by using more than 10%, naturally I felt that way , I also feel regretful for dying with just using 10% and born with 10%, why dont we change something about ourselves? This is not from any quote around the internet nor dictionary but from my own experience as a child and teenage but I believe that I had increased the percentage of my brain as I grow up. If my instinct were true , the fact that human uses 100% of their brain power will not be accepted unless human can use more than 100% . But of course, I dont think I had used more than 100% of my brain power. So, Ive made an experiment since last holiday. Ive started to play brain games around the internet to see if those specific game could increase my brain power especially in speed, memory, flexibility , ect. It really worked, I played it the whole week, not only I can get more point each day, but In the real life Ive also increase all the main categories. For example,when my pencil fall down around my deck, I would have realise nor able to catch it that fast even once. But I can do it now. So it proves, Its possible for human to use more than 10% of their brain if they train it.
