If you expect to be told what or how without taking the time to understand why, then you can also expect to often be deceived. When you are unwilling to think for yourself, there are plenty of people eagerly waiting to take advantage of you.
You have an extraordinarily powerful and capable mind. Go to the trouble and make the effort to make full use of it, particularly when it concerns your own affairs.
Life is increasingly complex, and you can't be expected to know every little detail about every little thing. But you will be vastly more effective when you take the time to learn the fundamental principles of what you're doing and utilize good, solid reasoning.
When it's your health, your money, your career, your property, your family or your future that's at stake, it's your responsibility to understand the situation. The person best suited to act in your best interest is you.
Certainly it is wise to seek the advice of experts. But stay away from anyone who promises to do your thinking for you.
Make the effort to be informed and then put that information to good, positive use. Think for yourself, and successfully live life on your own terms.
