Good, the game is suposed to be unfair, you may lose an arm, or a leg, or your eyes along the way. you may gain powerful special habilities, strong magical items, you may end up commanding an army, or living as a beggar, robbing travellers to feed yourself.
As for cheating, i always have my players control eachother if im in a hurry, if not i supervise the rolls myself, i know the temptation to cheat is strong, to start with an edge, to improve your chances, but at the end of the day it just makes playing the game pointless.
Play smart, good rolls wont save you, learn to let go, a character dies and you gotta roll another, learn that your character is in fact disposable until proven otherwise. Especially in a PnP environment. Be brave, playing it safe makes for your characters living longer, but will leave you with no stories to tell. Any player in their right mind would have retreated from that castle when they saw a fucking god being reborn, no one would have taken the chances i did, but honestly i was tired of being pushed back, that particular campaign was fairly ruthless and i just had enough, My character wasnt going to lose his friends over that, so he decided to make a stand.
Learn that no matter how high your stats are, in the bigger picture you are still part of a weak mortal race, and what you have means nothing.
Point buy is shit, it takes away a lot of charm from character creation, and its only suitable in a video game.
