I think that gravity doesn't only pull us down physically, emotionally too. Then , the world we are living in offers too many reasons to get upset. A lot of people really don't live the life they want or need to be happy. SO, even if the routine is ok, we may long for that state, that life, those people, those things, we do not have.
But we definitely can not wait for all those to be happy, start by being happy and see how great things are.
PS I say that but today I just had the strong feeling of happiness after days of complaint and being sick with all my kids. I looked around, my all family was together, the kids were playing, my husband was holding the baby and I was sitting with them...and I realized how happy I am when I don't dwell in Negative Land!
I also realize that I had a friend that used to really drag me down. I miss the good times but not having that negative interactions we built up our relationship on is a blessing. Yes, her negative energy used to turn into attacks if I was not complying in negative or complaining.
Edhan I agree so much, frankly, some people just suck the life out of you!
