I want to live in vagrant-like state

I recognized that all stuff around me I can merely recognize by sensory input, then it will constructed by my mind to a model of. Why not tweak this model to well=being manner? Hence I work to on tweaking my mind in such direction that I would become as happy as possible whereby it I would need material things as less as possible. So I'm at buddhistic track. Despite the fact that I think that at the overall game it's meaningless, because I think with death all reminiscences are lost. I close my eyes and count to 1. Such long endures eternity.
