I try to do one project at a time, but have found that it's just not possible unless it's something small. I find that the importance of a project changes as I progress on it. A pasture is important to get cleared and level to plant, but once planting season is over, that project loses it's place of importance and something else takes over. I've been working on fencing in my front pasture since I bought my land, but my grass isn't growing very well in places, so the fence has taken a back seat to other projects until I can get the soil corrected to grow grass.
Sometimes my priorities get changed for me. I've been clearing trees for roads, but we just got a new hot tub, so my wife changed my priorities for me and now I need to take out the old hot tub and put in the new one.
Other times, I try to stay focussed on finishing a project, but work and family sends me in another direction, and that project gets put off. I've been trying to build a deer blind since last spring. I started taking out trees where it's going to go, but then had the fan break off of my dozer while moving dirt. Then I had to build a prop for a play at the church that I do work for, and clean out my workshop for Thanksgiving. For an entire month, I didn't even look at my deer blind, but kept busy on projects that I didn't even knew existed when I started building the deer blind.
Yes, I prioritize my projects, but they keep changing around in their order on my list of which one is at the top of the list.
