Even though its prevalent in everyone's life what is different is the way people deal with it. Some deal with it in a positive manner whereas others find it difficult to live with it.
I know lots of people who have lots of things wrong with their lives...we all do. And I see a lot of them cribbing and crying about their lot in life. As though they are the only ones with problems. Life's a bitch....for everyone, and frankly cribbing about it is not gonna make it better....it's not gonna solve anything. All it does is make u feel more overwhelmed and unhappy. So whats the point?
There are others who just go along with a smile on their face and wait for it to pass. They don't make a big hullabaloo about it and just carry on doing what is needed to be done.
Learn to live with the fact that this is just the way it is and smile along the way...if nothing else it'll be a more pleasant journey than if you had spent it cribbing. If being unhappy doesn't lessen the lot on your plate then believe you me trying to be cheerful as you deal with it will not make that same lot bigger.
