There are several tasks on this morning's list. One of them you keep putting off, because you have already pictured how it will go wrong. You think of picking up the phone and hear the answer in your head: "What if he says no?" The tiredness arrives before the work does.
The Gita does not tell you to stop caring. It gives you something to do. Give just one task today three moments: one line before you begin, one line in the middle and one line when you finish. That is the whole practice for today.
What the Gita asks of an ordinary working day
मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ॥ २.४७ ॥
You have a right to perform your prescribed duty, but you are never entitled to the fruits of action. Never consider yourself the cause of the results of your activities, and never be attached to inaction.
The Lord tells Arjuna that his right is to the work and never to its fruits (Gita 2.47). In plain terms, the doing is in your hands and the outcome is not. What this means is explained in Action Without Claiming the Fruit. Here we put it to use.
The Lord also says that staying level in success and in failure is yoga (Gita 2.48).
Three lines for one task
Before: "This step is mine; the result is not." The line gives the work its true size. You are no longer carrying what belongs to someone else.
During: when the mind runs off to the result, say only "next step" and go back to the work. A person who has let go of the fruit stays fully engaged in the work and is still not bound by it (Gita 4.20).
After: as soon as the task is done, say, "My part is done."
निराशीर्निर्ममो भूत्वा युध्यस्व विगतज्वरः ॥ ३.३० ॥
Dedicating all your actions to Me, with your mind fixed on the Self, free from expectation and the sense of ownership, and free from mental fever, fight.
This verse is where that last line comes from. The Lord asks for work done without expectation, without the sense of "mine" and without the fever of worry (Gita 3.30). The full meaning of handing work over is in Offering All Actions.
What this is not
It is not carelessness. The Lord calls yoga skill in action (Gita 2.50), so the work gets the same care as before. It is not pretending that you do not mind: you do mind, but worry loosens its hold. And it is not a trick for getting the result. You are handing the result over, not bargaining for it.
An example: Kavita and the supplier's call
Take Kavita, who looks after her family's stationery shop. An order has come late, and she must phone the supplier. She has put it off for two days.
Today, before she picks up the phone, she says, "Making the call is my step; his answer is not." In the middle of the conversation her mind slides toward worst cases. She says "next step" and returns to what she was saying. The supplier says the order will come only next week. Kavita puts the phone down and says, "My part is done." Then she takes the next step and asks another supplier. His answer was not what she wanted, but the rest of her day was still hers.
Choose one task for today, the one you most feel like putting off. Before you start, say: "This step is mine; the result is not." If the mind runs off in the middle, say "next step." When you finish, say: "My part is done." At night, only notice when your mind ran ahead. Nothing needs correcting.
If you forget by the afternoon
Forgetting is natural. Begin again with the next task, with the same three lines. That is practice: doing the same small thing again and again. It will not settle in a day, and it is not supposed to.

The four moments of a whole day, the evening review and a plan for the first week are in the detailed reading. This topic is the last step on The Path of Karma Yoga.
