General Resolutions # 1

I once compelled myself to do everything that I had planned for each day. Every night, I thought about what I would do the following day and wrote them down in my diary. There were always little spaces right beside my task list to tick off the tasks once I had done them.  I am certain that it gave me great motivation to lead a productive life. From the moment when I opened my eyes, I ceaselessly thought about how I could achieve all of these things. I was very absorbed in clearing each task that I had done away from my diary. This daily pattern made me work untiringly / with inexhaustible efforts. When I was not through with (If I did not complete?) the day's schedule, I sneered at? myself. Back then, I was gripped by some obsessions clasped me tightly-when I fell short of the day's standard, some (ineffable shiftlessness held out?) during the night.

On the subject of my obsessions, I have some stories; I was very forced to study all day in high school, but I didn't do my best because I didn't understand why I should study and what I had to dedicate a lot of time to studying for. All of the teachers lectured me interminably about why we should try to save time. However, I didn't listen to them and instead, still submerged myself in doing other activities.  Looking back, I don't regret doing other things but I still brood over the fact that I didn't even try harder. With the passing of time, I can now admit to myself that I tried to draw back from facing (my initiative work-study for entrance? don't understand this phrase). I thought I had taken more than enough tests, but my relatively bad scores dismayed me time and again. Actually, I didn't try that often but helplessness permeated me even before I tried something (different?) to get a better score. I was (stumbling over my own imagination - perhaps - the barriers were all in my mind); the failures in the future which nobody was sure of would happen.
After I realized this, a sort of single-mindedness took hold of me.  From then on, I cherished time above all. I dreaded doing nothing because I felt like I would make the same mistakes I made in high school. I was appalled by the thought that I had already wasted a lot of time in the past. For a long while, I didn't mingle with people just so that I could clear my schedule.  I ended up losing touch with friends because I had to use all my time to finish a lot of things I'd decided to do. I was still entangled with? (obsessed by?) the most regretful moments in high school, whereupon - (this word is wrong and I lost the sense of the sentence) I could live a productive life. My heart had become marred by acute perfectionism and a lack of solidarity with my friends.

You are very expressive in writing about emotions. Well done!  

You are using advanced language and often it is important to choose good collocations.  MaY I recommend that you learn some collocations and try to use them. This may limit you to begin with but you would then build up more knowledge of natural expressions.

You tend to "sneer at" others, not yourself. Perhaps you meant "mock" or "criticise"?

"ineffable shiftlessness held out" You might have meant "restlessness".  I am not sure what you mean by "ineffable" but it is a very poetic or theological word and I wouldn't use it with "restlessness".  

Best wishes, Michael

I once compelled myself to do everything that I planned for the day. Every night, I thought about what to do for tomorrow and wrote them down in my diary. There was always little space to mark for checking right beside the list of my schedule. I am certain that it was a huge motivation for a productive life. From the moment when I opened my eyes, I ceaselessly thought about how I could achieve all of these things - I was very absorbed to clear each task from the schedule that I had done away from my diary. This daily pattern made me work with inexhaustible efforts. When I was not through with the day's schedule, I sneered at myself. Back then, some obsessions clasped me tightly-when I fell short of the day's standard, some ineffable shiftlessness held out over the night.
On the subject of my obsessions, I had some stories; I was very forced to study all day in high school, but I didn't do my best because I didn't find a reason to study and why I had to dedicate a lot of time to studying for. All of the teachers addressed interminable speeches over why we tried to save time. However, I didn't listen to them and still submerged in doing other things. As for now, I don't regret doing other things but I still brood over the fact that I didn't even try harder. As time lapsed, I admitted that I tried to draw back from facing my initiative work-study for entrance. I thought I had haddone enough of many trials, but my relatively bad scores dismayed me over again. Actually, I didn't give it many tries but helplessness permeated me even before I tried something to get for a better score. I was stumbling over my own imagination; the failures in the future which nobody was sure of would happen.
After I realized this, a sort of single-mindedness took me up. From then, I cherished time above all. I was in dread of the moment I was doing nothing because I felt like I did the same mistakes like when I was in high school. I was appalled by a thought that I had already wasted a lot of time in the past. For a long while, I didn't mingle with people to clear my schedule up. I ended up losing sight of friends-I had to use up all the time to finish a lot of things I'd decided to do.
