Reflection

I am ashamed to say that all my classes are suffering from my procrastination.
Even though i worked 24hours a week, statistically i had enough time to do all my school work and to study. But I have been very unstable in using time. At this time due to my procrastination I am swamped with late assignments. Thankfully due to the grace and mercy given by my teacher I am able to turn them in late with only a little penalty.
I know it's possible to get all my late works done and get caught up within a week. But thinking about them still gives me a big headache. Sometimes i'm so overwhelmed that i just want to quit school. Yet, I know it's not an option that i can so easily choose.
Even this blog is late but by completing this blog i know that i have one less assignment to worry about. I will try to be caught up by the end of this month andno more slacking off for me.
I don't want to be always stressed because of all the work that have accumulated.
I even cut my work hours to 8 hours a week so that i can use those times to study and not fall behind in school.
I thank God for providing for my needs and giving me another chance. I really want to be a changed man by the end of this month.

Encounter with Barry Black

I think it was four years ago, the last time i met Dr. Barry Black. He was preaching during chapel at Pioneer Memorial Church in Berrien Springs, Michigan (Andrews University). I didn't get to talk to him personally. But I read his autobiographical book and knew somewhat about him. He has been blessed with photographic memory and thus able to recite the whole bible, both old and new testaments, from memory. I thought that people with these kinds of abilities are disabled in some other way. However I could find no flaw in him. He interacted with people normally, talked, sang, walked normally. And as far as i know had no problem doing any other ordinary tasks. And so I found some articles and websites regarding people with photographic memories. Sure enough some things I didn't know before was that the original term for it is Eidetic memory. People with eidetic memory don't have to be autistic. But I was associating autism with it because the only people that are widely known to have this ability are autistic savants. I also found out that this phenomenon is still scientifically non explainable. I sure wish i had this ability as well. But only very few are fortunate of having this ability.
