When asked why HaShem created people, you get the strangest answers; all wrong. The top two are: "To serve Him" and "To do Torah and mitzvos." Puh-leeze. First of all, HaShem doesn't need any servants. After all, if there is a dirty dish in the sink, He must have created it, so I guess He wants it there. Generally speaking its best not mess with something complicated if you don't know what you are doing. The whole of creation is pretty complicated, so my advice is to leave running it to the experts... er, Expert, in this case. As far as Torah and mitzvos; those were created for you, not the other way around. So why did HaShem create you? To have fun; lots and lots of fun. That's not my opinion, that's the second sentence in the first chapter of M'silas Yesharim: Our Sages of blessed memory have taught us that man was created for no purpose other than rejoicing in HaShem and deriving pleasure from the splendor of His Prese...
This is a paraphrase of the pasuk in t'hillim 84:7 -- "mei'chayil el chayil" -- which means "from strength to strength". In this case, it is my thoughts and ideas to those who are strong enough to be interested :)
