What About The Idea Of Borrowing Happiness From Tomorrow

“O best of the Bharatas, now please hear from Me about the three kinds of happiness which the conditioned soul enjoys, and by which he sometimes comes to the end of all distress. That which in the beginning may be just like poison but at the end is just like nectar and which awakens one to self-realization is said to be happiness in the mode of goodness.” (Lord Krishna, Bhagavad-gita, 18.36-37)
