Ever prefer to be just in present?

Lately i have been took up with life and got into so many things. And i realized to be happy or to be not sad you just have to be in present simple as that.

But what makes it tough is your thoughts! To simply put when you watch a movie, when u talk to a friend, when you doing something you like, you will just be in the moment. Time don't work there.

Lately i have been doing lot of research and studies over the spiritual side of this and seems like a whole new world exist from it.

Anybody trying to do the self discovery?
