Creative thinking can also mean the realization that there is no particular virtue in having things done the same way all the time. Creative real estate does not mean some unethical or illegal way of acquiring property. It simply means doing it in a way that defies conformity. It's taking the road less traveled which is now covered with pebble stones but soon will be paved for so many people on their way to homeownership.
Your thoughts should not control you. Thoughts are things and you can create them or avoid them consciously. If you can learn to monitor and control your thinking, you can create that which you want to manifest in your daily lives. Increasing your awareness of your own thoughts will allow you to have that which you desire.
