Not to decide is to decide not to. This dynamic has been made real in your life more times than you can count, yet you still seem plagued by indecision and resulting inaction. Oh, you can call it lazy, but what's really at stake here is nothing less than your self-image, washed away by uncertainty and the fear that you don't really matter, after all.
You simply follow the path of least resistance, passively taking the easiest route, which usually leads downhill, in more ways than one. How easily less scrupulous people can take advantage of you! Learning to be more savvy and streetwise will help you take better care of yourself. Avoid drugs and alcohol at all costs, for down this road lies -- well, nothing good. When you finally do take action, it's based on some untested belief or a lofty and impractical ideal, so often your effort is squandered with no real results, only great loss of time, money and effort. If you can make some positive adjustments to your ideals, your actions will be more meaningful.
