Jack thinks about the past and the present and the future, there are many things that he would like to have done / do with his life but he fears that it may be too late for any of them.
Jack hates his job and he is not particularly fond of his life despite how technologically advanced he may seem to you. He wishes that something would change in his life soon. The government is working on some new technology lately maybe he could get his hands on some of that he thinks. It would change anyone's life greatly to be able to go wherever they wanted whenever they wanted.
