Both those ideas appear is some form in David Allen's GTD (Getting Things Done). I'm not a particularly big fan overall--I don't much care for systems. But some of his individual ideas include:

- the idea that, if you can do something in 5 minutes or so, just do it rather than keep putting it on to do lists.

- breaking down complex projects into discrete small concrete tasks.

Both are good ideas which do help me.

One thing about procrastination that often seems to be overlooked though is procrastinating about things that really do need to get done sooner or later (If I don't do the expense report, no one else is going to do it for me.) versus procrastinating about doing some project or making some plans because there's a voice questioning whether you really need to or want to do this project at all.

Now, I suppose in the latter case, a hyper-organized person would create an action item to "get more information" or something along those lines. But sometimes letting ideas just sit and percolate in a future projects queue works OK too.
