Hi I use GTD methodology since 2 years and I handle horizon 0, 1 and 2. I understand that horizon 5 is about my principles and values. All my tasks / projects must fit them. My problem is to understand how horizons 3 and 4 are handle other time. Let's take an example, I define my h5 with : "live in a house". We are in 2019, so I don't expect to buy a house before 2022. In 2020, I'll review my horizons. I still expect to buy an house around 2022. My horizon 4 move to horizon 3 ? On 2021, my horizon 3 move to horizon 1 ? Or horizon 4 still horizon 4 until my vision is fulfill ? And it triggers (or not) project on lower horizons ? When I listened webinar on GTD Connect, she talked about one horizon of David Allen : trip to Italy. She said that "trip to Italy" was on his horizon 4 list then on horizon 3 and finally on horizon 1 So I'm little disappointed, how to manage horizon during time ? Are they only projects lists to move other time or h4 is a real vision ? Thank for your enlightenment.
