Broken vacuum cleaner, broken glasses, broken frames...
Will you repair them? If you can't, will you take them into a repair shop? How often have you done so?
Look as objectively and honestly as you can at how often you actually did do this. How often did a broken item get repaired to become useful once more? I bet you can sum those times up on 1 hand.

Maybe you have bought the same thing to replace the broken 1. Let go of what is broken when you know you won't get to fixing them.
Because some things simply can't be fixed.

Make a list of the items that you keep but that are broken and you think of repairing 1 day.
If an item could still function after some tinkering give yourself A TIME LIMIT in which you will have to fix it. If after a month you still haven't fixed the 1 st. item on your list you either Throw Away or if you know someone else can fix it and use it, Give Away.
So make that list and write down the item with the date it should be fixed, if it isn't fixed by then deal with it like said.
This way you will have undeniable proof that you didn't do what you intended to. The more realistically you are able to look at your behavior the better. That way you won't be able to fool yourself that you simply didn't get enough time to attend to repairing something.
Face yourself with facts and not with broken promises.
