Prioritise
We all have mental lists of the things that need to be done. When there is too much going on we begin to feel overwhelmed and stress and panic can follow. How will we get it all done? So, learn to do what is actually necessary to do now and concentrate on achieving those priorities.
To help decide what these need to be, make a list of all the things that need to be done. You might want to make a personal list and a work list. Once written down number them in the order of importance.
Then apply a simple check list to each of the numbered items. (1) Can I pay someone to do this (2) Can I delegate this (3) do I have to do this now (4) Can I re-schedule this (5) Does it have to be done at all.
When we really examine the best way to resolve some of the many tasks we feel we have to do, we often find that they are not always as impossible as they would at first seem. It is often surprising that what we have left on our list is actually achievable thus reducing our stress.
