While some can take this to an extreme, one can't continually work with incomplete projects and actions around one. As well, one can't have people on your lines who simply can't or won't complete things. Root of this appears to be a non-confront of the job at hand, which might manifest as an inability to organize things.
An alternate point might be a lack of resources to get that task completed. In that case, the task is getting done at a very sloooow rate and looks to never practically get completed in a single lifetime.
The opposite of this also appears insane - the necessity to get things wrapped up very, very quickly - even if they didn't need to get done to begin with.
Cure for this is to work up lists of incomplete cycles around one. Go through this list and organize by what can get done quickly and which of these are more vital to current living. One will also see some of these are recurring cycles (or should be). At the bottom of the list are the hard choices - which of these that can't be done need to be simply dropped, or reviewed and finished as a smaller version.
Confront is simply looking at things head on, as the word implies. Improving confront is done by directly ones attention to that object and nothing else as a discipline. Sitting in a chair and looking only at that object until one can do it comfortably is one way to accomplish this. Another is to keep reviewing and analyzing a single idea until the solution is simple and obvious and easily executable - a "Eureka" moment.
But people on your lines who won't complete actions or won't let you complete yours have to be handled. One way is to limit your association with such. If they are a family member, one would work out agreements with them such that you have certain time(s) during the day where you have to yourself. Or get an office in a different building from your home, with no TV or distractions in it.
With many projects which are taking a long time to complete (that may interfere with one another), a simple solution is to work up a schedule daily and weekly/monthly to work on these. One might have many hats to wear in an organization. Working on these on a schedule and in rotation will tend to get these done until you can get/afford some help and groove them in on one or more of them.
Such handlings need not be extreme. Often the beginning to handling such work is to simply clean your room and place/organize things so that you can find them and get to them easily. Then work out a realistic schedule to get them all accomplished, as above, which will weed out the unnecessary or trivial projects.
Below this is your own vision of what you want to accomplish. Often getting this in view and then working out your own plan of how to accomplish this will give you a metric to compare the value of all the things you are trying to get accomplished so that your weeding can take place. Without a vision to anchor yourself, often one might feel like one is very busy getting all these things done but no morale which accompanies the satisfaction of a well-completed project.
Below the vision are the necessary plans to get such visions executed - plans which are both long and short term in length. Longer term plans can and need be revised over time as resources shift to accomplish them. Plans can be made to acquire resources. But complete planning is also a part of any personal vision. This is a subject of its own and deserves its own write-up.
At this point, getting things done in one's vicinity - as well as limiting exposure to those people who consistently don't get things done (while perhaps clueing them in on the above) should speed up one's production and as well enhance one's personal morale.
Luck and Good Hunting.
