Time to get my act straight.........

It is seriously past time to get my act straight,I mean I've literally wasted 19 years of my life.Where all my other friends have started concentrating on what is most important to them I still keep thinking about superficial matters like what happened in the past or what people around me think of me....
I have got to get a life!!!!!I have no idea why this hit me so hard now but i realized I'm just literally wasting away....I think of the 26\11 tragedy and I realize that life is way too short,you never know what will happen in the very next minute...
Starting right now or let's say tommorow I'm going to start concentrating on me..get my grades straight..start actually working on loosing weight instead of simply cribbing about it to friends who are starting to get really tired of it,stop thinking about what happened in the past and stop cribbing about that also to friends(the more I crib the more it shows i care..and i don't want to...)
This is like my last teenage year and I have to make the most of it..these are times I will never get back and I don't want to regret it later...
So I'm going to stop junk food(my friends are going to be so happy)..Work out(I am gymming now but doesn't seem to be of any use..)..Attend tuition regularly(I've joined a really pathetic college so I better start attending at least tuition regularly if I intend on clearing my enggineering with good grades..)Keep my room from becoming a mess every freaking day(This is really a problem..Most of my friends come home and look at the state of my room and leave again..so I'm going to make my room a very nice clean and tidy place where people can come in and not leave coz they might puke if they stay more than a sec in my room..and I'm so not exaggerating)
So let's hope I have finally got some sense and get my act straight..(You think i've used the phrase too many times??)..zand lets hope I do it before my 20th b'day...
