I've found that it helps tremendously to look at every single aspect of life and really understand everything there really is to know - knowledge is the key to any of life's questions.

It's important to note that there is ALWAYS something fundamental that you can learn from any topic, even if you may not know it.

When I first learned about the ideas of fitness and nutrition, it completely opened my eyes - particularly with the paleo diet and how the human race has been conned into so many false presumptions i.e. that saturated fat is bad for you.

The financial system is another example - perhaps my most prominent one - which has completely blown my mind. If you can understand finance, you can understand how the world works and functions, not only politically but every single kind of corruption out there. After all, "money makes the world go round". This then branches into so many other things

Of course, I'm a naturally curious person, so this works well for me. But the idea is that you can always learn something incredibly important, from anything.

You never know. You might even discover new passions.
