If I feel frustrated or stressed, I listen to this type of music: Happy video game music. If I have resentment for another person then I will listen to something like this: Walking sword anti resentment.
I also draw pictures and write blog posts as a hobby. I recently brought my two hobbies together, a good hobby can change your life.
I like to read a lot of books; I think that the more books you read, the happier you will be. I have two book shelves. I have a digital book shelf and a real one. My E Reader is very light and has a back light so it is easier to read at night, I don't need a reading lamp to read it. I also like to read real printed books, sometimes I get interesting factual ones in charity shops for about 50p.
Books that are very interesting to read are Factual Journals and back stories to sci-fi movies. 'Who goes there' by John Campbell is the original story for my favourite movie, 'The thing' from the 80s. I also liked books by Gary Zukav, 'Dancing Wu li masters' is very interesting. I read through '23 minutes in hell' by Bill Weise, he is a guy that claims he was taken to Hell for 23 minutes.
Read more and be happy.
