I've been told that the best way to get things done that you may not want to do is to just assign good outcomes to them and keep those outcomes in mind. Lets say you wanna get a report done but it's about something you couldn't give less of a shit about. Just tell yourself, and mean it, that you're gonna get like, a game or something afterwards. That way you're doing what you need to do while getting things that you may want faster. Also, keep in mind the consequences of NOT doing them. Do you really wanna have to deal with them not being done right or not done at all? Most people don't.

If that doesn't work for you you could just start telling yourself to get off your lazy ass and just do the dam thing and get it over with so you can go back to whatever it is you were or want to do.
