...is used against feelings of exhaustion and tiredness that come before an effort has been made.
The person in this state feels weary when he looks forward at the demands of the day. It's easier to stay in bed or put off making a start, or find other things to do - but if an effort can be made to get started the weariness will fade, a sign that unlike the Olive state this tiredness is wholly 'in the mind' and can't be traced to actual events in the real world.
Dr Bach's description
For those who feel that they have not sufficient strength, mentally or physically, to carry the burden of life placed upon them; the affairs of every day seem too much for them to accomplish, though they generally succeed in fulfilling their task. For those who believe that some part, of mind or body, needs to be strengthened before they can easily fulfil their work.
