I would declare revolution, rule the whole world, kill all the leaders who rule nowadays, unite all nations in a one nation which i'd be it's leader to prevent wars and usless bullshit, money would be in one currency and would be shared equally, would ban social media, p*rn sites, any usless technology that is more useless than useful, give women the same rights they had in 60's, so unattractive men would have chance to have love and sex, ban feminism, LGBT and every other bullshit movement, would mercilessly kill anyone who tries to cause any conflicts or problems or wars, all weapons, bombs, etc, that cause harm and suffering would be banned and anyone who tries to break this rule would be killed, ban gay marriage and transsexuals.
I honestly would do a lot more, but it would make this thread too long and boring, so..
I know most people would hate me for this, but i don't care as long as peace would take place and the world would be million times better.
