Four steps through the Bhagavad Gita for the dread of a result you cannot control: the right to work, evenness of mind, skill in action, and renouncing the fruit.

Step 1

Bhagavad Gita 2.47

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन। मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ॥

karmaṇy-evādhikāras te mā phaleṣhu kadāchana mā karma-phala-hetur bhūr mā te saṅgo ’stvakarmaṇi ||

Your right is only to work, but not to its results; do not let the results of action be your motive, nor let your attachment be to inaction.

Your right is to the work, not to its results. Ask which part of what worries you is the work, and which part is the result.

Step 2

Bhagavad Gita 2.48

योगस्थः कुरु कर्माणि सङ्गं त्यक्त्वा धनञ्जय। सिद्ध्यसिद्ध्योः समो भूत्वा समत्वं योग उच्यते ॥

yoga-sthaḥ kuru karmāṇi saṅgaṁ tyaktvā dhanañjaya siddhy-asiddhyoḥ samo bhūtvā samatvaṁ yoga uchyate ||

Perform action, O Arjuna, being steadfast in Yoga, abandoning attachment and balanced in success and failure; evenness of mind is called Yoga.

Krishna asks Arjuna to act while balanced in success and failure, and calls evenness of mind Yoga. Ask what evenness would change about your next action.

Step 3

Bhagavad Gita 2.50

बुद्धियुक्तो जहातीह उभे सुकृतदुष्कृते। तस्माद्योगाय युज्यस्व योगः कर्मसु कौशलम् ॥

buddhi-yukto jahātīha ubhe sukṛita-duṣhkṛite tasmād yogāya yujyasva yogaḥ karmasu kauśhalam ||

Endowed with wisdom and evenness of mind, one casts off in this life both good and evil deeds; therefore, devote yourself to Yoga; Yoga is skill in action.

This verse says the one endowed with wisdom and evenness of mind casts off good and evil deeds, and that Yoga is skill in action. Ask what doing this one task well, now, would look like.

Step 4

Bhagavad Gita 12.12

श्रेयो हि ज्ञानमभ्यासाज्ज्ञानाद्ध्यानं विशिष्यते। ध्यानात्कर्मफलत्यागस्त्यागाच्छान्तिरनन्तरम् ॥

śhreyo hi jñānam abhyāsāj jñānād dhyānaṁ viśhiṣhyate dhyānāt karma-phala-tyāgas tyāgāch chhāntir anantaram ||

Better indeed is knowledge than practice; better than knowledge is meditation; better than meditation is the renunciation of the fruits of actions: peace immediately follows renunciation.

Chapter 12 ranks knowledge above practice, meditation above knowledge, and renouncing the fruits of action above meditation, and says peace immediately follows renunciation. Ask what it would mean to let go of one fruit you are holding.
