(Haggai 1:5-6) “Now thus says the LORD of hosts: Consider your ways! You have sown much, but have brought in little; you have eaten, but have not been satisfied; You have drunk, but have not been exhilarated; have clothed yourselves, but not been warmed; And whoever earned wages earned them for a bag with holes in it.”
A life of just doing stuff without including the LORD will never be truly fulfilling.
