On action

तस्मादसक्तः सततं कार्यं कर्म समाचर । असक्तो ह्याचरन्कर्म परमाप्नोति पूरुषः

Sanskrit

इसलिये तू निरन्तर आसक्तिरहित होकर कर्तव्य-कर्मका भलीभाँति आचरण कर; क्योंकि आसक्तिरहित होकर कर्म करता हुआ मनुष्य परमात्माको प्राप्त हो जाता है।

Therefore without attachment, do thou always perform action which should be done; for by performing action without attachment man reaches the Supreme.

Bhagavad Gita · Chapter 3 3.19

What it means

Do your duty without clinging to it — that is how good gets done.

Carry it today

Do one duty today fully, without making it about the reward.
