Please heed my advice -- DONT.
I have also been an avid maplestory player in the past. I know
how it feels like, the feeling of self gratification and
accomplishment, the exhilarating and relaxing time spent in it with
virtual or real friends. But in the end, you would be left without
nothing but loneliness and regret for your entire life.
Knowing that your studies are already jeopardized by excessive
gaming, I think you have already realised the negative impacts
gaming has brought to you. As any other addiction, I know it's
still very difficult to stop, but you must quit.
Too many lives were already destroyed by gaming.
I strongly encourage you to google "gaming addiction stories"
and read some of them. Besides that, I find that those who lack
determination often has not powerful enough desires to start with.
Apart from gaming, what else do you like? Have a meaningful and
significant goal in your life, and believe me, gaming does
not and cannot last forever. 99% of addicted gamers would
wake up one day and only find it to be too late. Their life was
half gone. I was fortunate enough to have wonderful parents who
stopped me in time. Perhaps you can approach your parents?
In the end, games are nothing but meaningless long pages of
computer programming. All those colourful & attractive
graphics, the quests, the leveling up, the abilities. They are just
meaningless sequences of 26 alphabets & 10 numbers that will
make you regret for life. So please quit it once and for all.
Best wishes.
