Overwhelming number of things to do

Why is it some people seem to have their lives so well organized? I have problems with simply having too much on my mind. Something always gets in the way of me finishing things and they get put to one side and get added to my to do list which gets longer and longer. I worry constantly about paying bills I can't afford or dealing with administration problems.
My job is as a specialist craftsman and I'm up there with the best in the world but the huge complications involved in just making my work just adds to the problem. I have to fly all over the place which i hate so I have to think about all that. I also have to run workshops and sell my work directly to the public which again, adds to the stress. I do make lists all the time but that doesn't help. My contracts are always late and I'm forever being chased by people wanting commissions etc.
My wife is a non functioning alcoholic who does nothing except badger me to stop work and take her down to the pub and we row all of the time.
All these things leave me feeling as if I'm constantly patching the holes but never fixing the problems..

If anyone has any ideas how to manage this type of problem I'd love to hear about it?

having money undoubtedly makes life a lot easier. i live on a very limited budget and constantly have to think carefully about the simplest of decisions where money is concerned. when i was working such considerations weren't an issue but living as i do now they're ever-present.

in terms of people in general, to a certain extent they just have to be tolerated. you don't have to give more time and effort to them than they deserve, however, you can't escape them completely, especially if your livelihood depends on them.

as for your wife, perhaps you should consider whether this is a relationship that you want to continue, after all, you don't seem to have anything positive to say about it. alcoholics are notoriously difficult to live with. somehow, their addiction is all that matters to them. but, as with any addiction, it's the addict that has to want to change.

in summary, it seems to me that you need to find more time to yourself to get a clearer perspective of your life. i would strongly suggest that you try meditating, assuming that you don't already. this may give you the opportunity to gain a fresh insight into your situation and allow you to move forward. but what is clear from what you say is that something needs to change. i will add that having lists is often of little value if they aren't prioritorised. in other words, decide what matters most to you and focus your efforts on that.
