Don’t let my list read what follows or it will be laughing hilariously at me the next time I pick it up, saying to me “I can’t believe you actually hit enter on that post. I’ve gotten so fat you hardly ever look at me.” 🙄
Since I have a weed eater and know that it (and the chain saw) can be a problem, don’t put that at the first of your list. You might even start the thing the night before to make sure it is going to work. Sort of like getting things in order for the next day’s work. Lawn mowers are more reliable than weed eaters so cut the grass first rather than weed eat. That way something will get done. 
Break up the tasks. e.g. Mow front yard, mow back yard. Then you may be able to check off at least part of the task. As someone mentioned elsewhere, instead of having clean house on the list, break you list up by room or by time spent. Keep a list of things you have done successfully. That way, you can build on successes throughout the week, rather than tripping over the one thing that is problematic. This may give you a better frame of mind when you “fail” at an item. So rather than seeing a big failure on a major part of that day’s list, it will look like one item out of twenty for the week that didn’t get done. 😉
As for weeds, this is how we do it. Basically put mulch around all the plants out to the drip line and spray it with roundup when weeds start to come through. Last year when the tree trimmers came through trimming all the powerline right of ways, we told them to dump all the ground up shredded trimmings over next to our garage. We got maybe 30 truck loads plus firewood for several years. It saved them maybe a 30 mile drive to the dump and we ran out with cookies and Cokes when they came. They even sorted the firewood out for us. All the grindings make good mulch which composts down as food for the plants. With the stuff out to the drip line, it is easy to mow around and the roundup works well for keeping down the weeds so we don’t have to tend weeds every week as would be required with a weed eater. In the past, during the fall, everyone in town has their lawn raked and their leaves bagged nicely on the curb for us to pick up and carry home to use as mulch. Spraying is quieter and more satisfying than weed eating. (DIE WEEDS!!! DIE!!! 😈 )
