Life goes on and on...............,day after day......................,minute after minute...........on the track during the journey we see many great places met many good & bad people some of them accompany with us and with whom we feel very happy and satisfied. Some left earlier and depart................still life goes on same track specified direction...............things get change some times we feel bad, irritated, lazy but no one bother the journey goes on and on.....................suddenly the destination arrives and at that place we have to say goodbye to everyone whom we met during our journey...........
So the main focus and objective writing this all stuff is don't bother too much about the negitive assumptions and happenings its all part of life. Do take challanges and face problems.
Remember Every Problem has a solution if not then there is no need to worry about, like no lock is without a key 
Try to keep yourself busy you are just too young to bother such things at the moment.
Keep yourself and others happy
Life is given only once by Allah why not enjoy every moment of it instead of getting depress and makes ourself unhappy and people who loves us unhappy.
Think about it Bro.
