i have just realise that life is boring without any challenges

I totally disagree. There are always things to look forward to and learn. there is so much out there. I'm sorry you feel that way.

I don't think life would be boring, just maybe a litte easier. I try to keep things in order and eliminate any challenges that would make life harder.

well it depends on your attitude and outlook towards life . it is always ones interpretation of life . it is the case of the glass being half empty or half full . life springs up surprises at the unexpected moments and so just cheer up and play the beautiful game called life .life is indeed at times boring and harsh but at the same time it is a bundle of oppurtunity too . and one needs to constantly take up challenges , however insignificant it may be and work hard towards acheiving it . best of luck
