Fear of failure & results

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन। मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि॥

But you have only the right to work, but none to the fruit of it. Let not the fruit of your action be your motive; nor be you enamored of inaction.

Simple meaning

Krishna says: you have control over your effort, not over the result. Don't let fear of, or greed for, the outcome become the reason you act, and don't use that fear as an excuse to do nothing.

In real life

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

Perform all your actions with your mind concentrated on the Divine, renouncing attachment and looking upon success and failure with an equal eye. Spirituality implies equanimity.

Simple meaning

Krishna asks Arjuna to act while staying steady, treating success and failure with the same calm. This balance of mind, samatva, is what he calls yoga. You still give your best, but your peace doesn't depend on the outcome.

In real life

सुखदुःखे समे कृत्वा लाभालाभौ जयाजयौ। ततो युद्धाय युज्यस्व नैवं पापमवाप्स्यसि॥

Look upon pleasure and pain, victory and defeat, with an equal eye. Be prepared for the combat, and you will commit no sin.

Simple meaning

Krishna tells Arjuna to see pleasure and pain, gain and loss, victory and defeat as equal, and then to do what must be done. When you stop being ruled by the outcome, you can act cleanly and without guilt.
