Thanks James - interesting.
OK, so to get clear, your calendar is on a totally different system, yes?
And if so do you carry any data into each block on your calendar saying what you will be doing in each block of time?
PS Here's something for the procrastinators amongst us:
Although I definitely don't think I've cracked how to execute GTD well, one thing I do that might help others is that I have a special Tag that I apply to 'live'/'Do ASAP' tasks which I call "Frogs". (From "Eat that Frog" book). For me these are 'high-resistance' tasks, which I define as anything dull that I have already put off doing a number of times. (!)
I tackle my Frog tasks slightly differently:
1. I like to do at least one these 1st thing/after food (when Willpower is stronger)
2. I sometimes allocate a small 'reward' to self for their completion
3. For BAD Frogs I eventually allocate what I call "DNB" time ("Do Nothing But") meaning I don't HAVE to do that task but I am not allowed to do anything of ANY sort else. No phonecalls, no food, no drinks, no interruptions of ANY sort...
==> I am do not allow myself to do anything else whatsoever during any DNB time block.
From time to time, I allocate a general-purpose 'Frogs' time-block. The psychology of this is slightly different. Here I 'ambush myself' by allocating say 45 minutes during which time I commit to doing the following:
A) Sort my task such that whatever Frogs I put them into the order of (roughly) how many times I think I've put each them off.
B) Execute whatever is at the top of the list for the remainder of those 45 minutes.
This is good because my subconscious mind hasn't had time to come up with excuses as to why I can't to whatever that task is just now... and so you just do it!
Potentially a slight sledgehammer to crack a nut but personally I find the above can be extremely useful.
