Same here. Long ago I realised that I have a tendency to procrastinate when faced with having to do things I don't want to do (while conversely being quite good at being focussed on the things I do want to do). Time management only comes into it in the the sense that I want to spend less time doing things I don't like and more time doing the things I do like. Doesn't seem a particularly surprising piece of self-insight to be honest. So, when I realise I'm procrastinating, i.e. faced with something I don't want to do, questions are: Do I really have to do it? If I really have to do it, why don't I want to do it and can I make it any less bad? And if I have to do it and can't turn it into something I really want to do, why can't I simply just get it done and out of the way so I can get on with the other things I actually want to do instead? I wouldn't be surprised if this was generally applicable to some or many other people too.
