Chapter 18 · Liberation through Renunciation · Krishna said
Bhagavad Gita 18.48 — Every task has flaws
सहजं कर्म कौन्तेय सदोषमपि न त्यजेत्। सर्वारम्भा हि दोषेण धूमेनाग्निरिवावृताः ॥
sahajaṃ karma kaunteya sadoṣamapi na tyajet | sarvārambhā hi doṣeṇa dhūmenāgnirivāvṛtāḥ ||
Meaning
O Arjuna, do not give up the work natural to you, even if it has flaws; for every undertaking is covered by some fault, as fire is by smoke.
In today's life
No job is free of flaws — when you see them, keep doing your work honestly instead of walking away.
