One must be fully focused on ones own duty. Ones swadharma. Lord Krishna calls this out in the 35th verse of the 3rd chapter of the Gita. Here’s an excellent take by Shri Vinoba Bhave in his book called “Talks on the Gita”. He gave these talks when he was jailed for being a part of India’s freedom fight movement!
It is not good for me to adopt another's dharma, however superior it may appear to be. I like sunlight. It helps my growth. I worship the sun. But my rightful place is here on this earth. If I leave the earth and try to get close to the sun, I would be burnt to ashes. Compared to the sun, the earth may appear worthless; it may not be self-luminous, still I should strive for self-development by staying on the earth, which is my rightful place, so long as I lack the capacity to stand the sun's powerful blaze. If someone were to say to a fish, "Milk is more luxurious than water. Come and swim in the milk", will it accept? It can survive in water only; in milk it will die.
