I could try to say to myself every morning I get up:
“What shall I do on this day in my life-journey?” (Or just: “On this day of the journey?”)
By doing so I train myself to see my life as a journey.
And for me a journey has always been something positive.
It has a goal. A meaning. Even if a lot of terrible stuff happens along the way and you get stuck for 3 days in an airport somewhere
