One brain can change the world... just one brain...

Im mad at people, im angry with them but my fight is not with people, my argument is not with people, its with the system. On Eid day i met a jew at a supermarket, we got into religious conversation, peaceful one, upon asking why is he a jew, he answered me, its because my parents were jewish, so am i. I hate groups, why, because they always talk non-sense and crap in groups. Our minds are set, our concerns are mindset. Our attitude sucks. We are forced to believe in things. We always swallow what our people have been pushing down our throat. Gist of my post is, we are losers, in this world and hereafter.
Lets analyze:
In this world, we are never trouble-free. Always stuck, always feeling low and gloomy. Money became our sustainer, our rabb.
Hereafter: The world is a test, im failing it. We are gonna face consequences of what we did here.
Our excuse: Everyone is doing it, why not me. Lets do it now i wont do it again.
Loosers we are...
I don't think i can change the world, but i can spark many brains that will change the world, i can create awareness that we people are wrong. Alhamdulillah, so far i have succeeded, plenty people are giving up their evil deeds....
Im writing this because today for the 1st time, i think i did achieve something. One of the dude i knew who had been drinking regularly, stopped drinking after lil lecture of mine. I told him about this mother of all evils, spiritually and physically, sideeffects and disadvantages, Islamically and wordly. He promised that he'll never drink or commit adultery again. His mind was changed. Thats what im talking about, cant change the whole world, but one brain at a time. Previously i changed many people, guidance comes from Allah, i was just a source or mean. Now those people have become sources of others... Its a MUST to invite people to truth. The people i converted to Islam had never heard of the word Islam ever before. They were like some lost sheeps with no shepherd. On the day of judgement when they are about to be thrown in hell. They'll say oh Allah, what was Islam, we did not know, no one told us, we drank, we committee evil sins, no one stopped us, whats our fault. Then Allah will throw those muslims who did not deliver Allah's kalima to others. We'll not enter paradise because we did not stop the bad things happening around us.
