Consider for one moment that everything in this realm is constantly changing physically... every step you, as an individual, takes leaves an irreversible mark on this earth. The definition of fluidity as an adjective is 'readily reshaped; pliable,' even the most solid thing we can conceive of, the very ground we tread every day, is fluid in physical nature. What I am suggesting is that they can't see the entire, permanent picture. If you believe in destiny and that you have a predetermined destination, that's fine.... the journey to that destination is what you and others can influence, for example; you want that job.... you may not get it right at that moment- maybe you didn't meet the qualifications, maybe the hr director's niece was also interviewing, maybe there was a hiring freeze from corporate and the position was terminated before the first round of applicants was interviewed, for whatever reason you didn't get it... that in no way means you won't eventually, if it was meant to be it will happened sooner than later. But all of those little things can can alter the path to that job, and most of them have nothing to do with you or anything you've done. What you are asking from these readers is to not just to tell you the destination and the general lay of the land, you are demanding to know every little in road and the location of every pebble that lay in the thoroughfare.
As to the inane questions, here is my smart ass answer: The best way to protect yourself is to not call psychics at all. A less jack-assish answer is this: If you trust in your own instincts and not become slave to predictions and and time frames you will find that your personal journey is a little less painful. As I have stated before; I've been visiting this forum for years. These threads are littered with tales of time frames that came and went and readings that never came to pass. It is very tempting to call everyday, but what good does that do you? I too have had predictions given to me that were such blatant fairy tales, that looking back I feel like such a fool. I have found readers that have been able to give me predictions that come to pass, within stated time frames even(!), but that doesn't mean that I put too much stock in the details or times they give me because I do not think that there is any one human being who can map out the future in its entirety in precise detail for even one person let alone several dozens. I think expecting to find one is like expecting to find a unicorn who speaks fluent English and is carrying a basket of leprechauns. The best you can do is find one or two who can give you the big picture and where you stand in it now so that you can make your way to that eventual outcome without to much harm to yourself or those around you. At some point, you do have to take the reigns and walk the path yourself.
