Thank you everyone.
I have thought about this and I am now going to try the following
Getting things done Side A in the morning before work
Peak performance during my lunch break
Both of these focussed on having lots of my next actions ticked at the end of the day.
Over the last few days I have been using New History Generator side B before bed. This has helped a lot. One of the reasons that I have not achieved all I could in the past is that I tend to switch off the consequences of what I am/am not doing. Eg not thinking about the consequence of eating sweets or not thinking about the consequence of leaving a report until the last minute. Since using NHG Side B several times now I have thought to myself "if I get on and do .... then I can review it tonight and it will feel good". This is a significant improvement for me.
I'll report back in a few days as to how I am getting on.
Regards
