A good result feels easy. A setback can shake you. Krishna asks Arjuna to act with a steady mind in both. Bhagavad Gita 2.48

योगस्थः कुरु कर्माणि सङ्गं त्यक्त्वा धनञ्जय। सिद्ध्यसिद्ध्योः समो भूत्वा समत्वं योग उच्यते॥ भगवद्गीता २.४८

Say it slowly Yogas-thah kuru karmani Sangam tyaktva Dhananjaya Siddhy-asiddhyoh samo bhutva Samatvam yoga uchyate Bhagavad Gita 2.48

What Krishna means Do your work without clinging to the outcome. Meet success and failure with an even mind. Krishna calls this balance yoga. Care about your actions. Let each result teach you.

When a result arrives Pause before you react. If it went well, stay humble. If it went badly, look for what you can learn. Then choose your next useful action.
