If the amount of money is so great for you that you are going to spend the whole time acting like you're double parked, you should not hire a consultant. I also had the experience of consulting for free for some friends and relatives. I gave them a number of pieces of advice. They followed some and ignored others, then blamed me when things did not work out as hoped. In each case, the problems were caused by their ignoring portions of my advice.
Victory has a thousand fathers, defeat is the consultant's fault .
Clients are welcome to reject my advice, but I will not work for anyone who appears inclined to reject portions of my advice, then try to blame me if that rejection causes them a problem. Accordingly, if someone wants me to consult, I will first question them closely as to exactly what they need and expect. I will probably turn down most consulting requests on the grounds that I do not believe I can provide what the client wants. In some cases, I have been able to be of great help to investors seeking advice. In others, I have told them I cannot help them.
