Misery will not leave from where there is excessive bad or harmful associations with that which takes you away from the Self (kusang). Whereas happiness will not leave from where there is excessive association with Self-realized beings or spiritual discourses (satsang)!

The fruit of the intent of serving others (sevabhaav) is worldly happiness, and the fruit of the intent of disserving others (kusevabhaav) is worldly misery. Your own 'I' (real Self) cannot be found through the intent of serving others. However, for as long as you do not realize your real Self, you should maintain an obliging nature.

One has to 'do' for worldly happiness, for material happiness. However, one does not have to 'do' anything for liberation (moksha) or to attain God. Yet what do the people of the present times teach? 'Do', 'do', 'do'.

Outer pleasure and pain is under the control of ‘Scientific circumstantial evidences’ and to have the inner peace [inner pleasure] is the result of one’s Self-effort (purusharth).

Physical pleasures are not associated with attachment-abhorrence; the belief in an opinion itself is attachment-abhorrence.
