The best way to know is to achieve KNOWLEDGE
Here is my suggested reading list that I believe everyone needs to have in their library. Reading is fundamental and can often provide the steps towards success. When you are traveling on your journey, finding your path, towards your highest self always look for confirmations and feed your mind, body, and spirit with the proper nutrients to remain strong during your travels.
