One of the key teachings of Śrīmad Bhagavad Gītā is Karma Yoga or consecrated action. It is action that is completely removed from selfish motives.
In Stray Birds, Rabindranath Tagore writes,
Either you have work or you have not.
When you have to say, ‘Let us do something,’ then begins mischief. 
There is always work to be done. Selfless work is the work that is done without burdening oneself with the idea I am doing something super-significant and awesome. On reflection, it is straightforward to see that it is a useless idea which only comes in the way of work and dissipates our energy fruitlessly.
Work has to be done because work is needed for survival. Work has to be done to avoid the devil of idleness and ruin. Work has to be done because the product of work is beautiful. Work has to be done simply because we can do wonderful things. Work is the labor of love; it is the gift of life. Work becomes great when it is not seen as great work.
He, who is too busy doing good, has no time to be good.
Work should not be done because there is a gaping hole in our hearts. It is not the outlet for virtue signaling. It is not a way to fulfill our narrow want to appear larger than life. This is why we are warned: the way to hell is paved with good intentions.
Work is an expression of life and of joy.
