In life wasting time is at the top of the not-to-do list. There are many activities and events that can waste your time, and I'll be giving you the top 3 main time wasters. I call it "The Triangle Of Wasting Time".

Going To Church: There has been a strong dogma that claims the believe in religion is rational since it is what humans will often come to believe when the answers to our origin is sought. It is not, a human like entity with magical powers that rules outside life is not a perfectly rational explanation for our origin. That is why a huge portion of people that believe don't even go to church. Inside they know it to be true. The belief is not based on reason, but on want. They wanted to be true so they ignore reason and logic. Jerking off and playing video games is a more efficient use of your time than church.
Going to Public School: If your purpose in school is to learn then avoid a public school at all cost. Why you may ask? Easy, it is run by bureaucrats, therefore it is not efficient and to be completely honest public schools shouldn't exist. They do not have the incentive private schools do. How well you do in a public school won't determine your life, your mindset will. Statist argue that public schools help the economy by educating the population. First propaganda is not education, second the internet has all the education you need, and third of all child labor helps the economy, public schools don't. The fastest growing countries all have child labor. The only excuse for going to a public school is to reach your goal for having a professional job working for someone else that you can only achieve by going to a public school, if you are poor. Next time a bureaucrat tries to teach you something remember he doesn't work in the private sector; he produces nothing.
Voting: You have a better chance of winning the lottery than your vote making a difference. Its not very CHAD to vote. CHADS only rule.

In conclusion don't waste your time.
