Meaning of Studying for better future

Well i chose this topic after looking at my class for a week.And i noticed tht some of them who were mischevious and naughty hv got better discipline this year and others who were mischevious hv become more of it.While some others who were better disciplined hv gotten well spoilt.Even though some of us remain same others change.Some of my colleagues do not understand the importance of there studies while others who hv seen an example and got disciplined.It was like this.One of my colleagues got repeated in grade 8 and another colleague of mine saw this and got scared or any other word tht fits there.Any ways now he is in to studying,hes a much better student and completes his work.But another of my colleague who was appointed to sit near me by our cls teacher doesnt even come close or even dont try to come close to the word "SOLIHU",i tell him a lot of things but he never listen.Even like tht is not enough he hates the subject TT so much tht he wont even touch the book neither he studies and disturbs me trying to not let me study.Well i told one of my past teachers and she said tht they wont get any better but worse.But stl if they try they can change.I guess theyll just learn the meaning of studying to face the world of working age group which is a big battle field of knowledge.Evry year its getting tougher and tougher to get a job and this is a big crisis tht they wud hv to face.Wat to do with them the school is tryingits level best to guide them on the right path i guess there are many other reasons for there misguidance.But i hope tht they wud at in sometime in near future they wud end up at the right path even by mistake.May God help them.
