Bhagavad Gita on Motivation

BG 2.37

हतो वा प्राप्स्यसि स्वर्गं जित्वा वा भोक्ष्यसे महीम्।

Slain, you will obtain heaven; victorious, you will enjoy the earth; therefore, stand up, O son of Kunti, resolved to fight.

BG 2.47

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन।

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.

BG 3.8

नियतं कुरु कर्म त्वं कर्म ज्यायो ह्यकर्मणः।

Perform your bounden duty, for action is superior to inaction, and even the maintenance of the body would not be possible for you through inaction.

BG 6.5

उद्धरेदात्मनाऽऽत्मानं नात्मानमवसादयेत्।

One should raise oneself by one's own self alone; let not one lower oneself; for the self alone is one's own friend, and the self alone is one's own enemy.

BG 11.33

तस्मात्त्वमुत्तिष्ठ यशो लभस्व

Therefore, stand up and obtain fame. Conquer the enemies and enjoy the unparalleled kingdom. Verily, by Me they have already been slain; be thou a mere instrument, O Arjuna.
