The two minute rule has transformed my working and writing life…
The question to ask yourself is: of all the jobs I have to do, which can I do quickly? (ie, in 2 minutes)
If you can do something in two minutes – then do it! No point having trivial tasks hanging over you, and it will feel good to get them out of the way… In fact, it will give you a sense of achievement and motivation that is likely to make it easier to get on with the harder stuff.
Then when it comes to the harder stuff, there are various techniques for dealing with that. Firstly, make priorities. What do you most need to get done? What is the most important task? What is less important and can perhaps be discarded (or delegated)… You can only do so much, so focus on the things that simply must be done.
And try to avoid procrastination (I have another post on that)
