There is one tactic and one tool I have been using to try and get on top of this and make myself more productive.
The first is “Do Something!” and I mean anything related to the task that you are meant to be doing. Without doubt, I find that taking that first step is always the hardest but once I start I always wonder what I was waiting for. I have been using this not only for procrastination but for other changes I want to make in my life. It always reminds of a quote that “You miss 100% of the shots you don’t take.”.
This is a great tool for keeping yourself fresh and motivated to get a task completed. It is a simple structure of alternating working with break times and all you need is a timer. It doesn’t need to look like a tomato!
Lifehacker has a great 101 of how it works. There is a book but it is a hard to find in the UK so I would stick with the 101 from Lifehacker. Also there is a great web tool that does all the timing for you, Pomodoro Timer. Give it a go and let me know if it works for you.
