Of course we all do have expectations from everything. We expect a lot of things in our life but if that is not going on our way then why to get upset or sad about it for a long time. So if you are letting it as it is you will be happy. That is not right for us but we still do so many things just to work out that relationship but deep down the name
Don't be sad about thinking what will happen in the future or what has happened in the past. Just live in the present and go with the flow. Whatever the situation is live in it and don't regret after that happened or don't think about the future you can't get anything out of it. There is no point of thinking about future or regretting about the past. So being present, live in present and do whatever makes you happy
