Use Your Brain

Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.
— Hindu Prince Gautama Siddharta, the founder of Buddhism, 563-483 B.C.

As human beings, it’s easy to stay comfortable, moseying along in our own little worlds simply believing everything from our childhood indoctrination. However, as an adult with the ability to reason, you can choose to examine your life. Look deep, grow as an individual and an intellectual by questioning everything you've ever learned...start asking yourself the hard and scary question: "why?"  - why do you eat the way you do, like the music you like, worship that god. You get the point. 

...question religion, question it all, question existence until them questions are solved...
— Jay Z, Heaven

Question everything and explore the world around you. Enrich yourself by experiencing the food, people, practices, and belief systems of different cultures no matter how ridiculous they seem. Because if you think your belief system is the only right way, think again; there are nearly 200 countries in this world with over 6,000 languages spoken. According to some estimates, there are roughly 4,200 religions, complete with their very own, unique creation myths.

Put aside your biases, your preconceived ideas and stereotypes. Open up your mind and analyze, observe, criticize, substantiate, and rationalize the world around you so you can come to your own conclusions, from a reasonable and logical standpoint. You owe it to yourself, at the very least, to broaden your perspective on life. All too often people forsake their own logic, reason, and common sense to stay comfortable in their own ignorance. Be better than that.

And although we may never know why we exist, we can certainly find meaning, purpose, happiness, tranquility and joy in this life while we're here. 

Happiness is a journey, not a destination.
