You are right. It is not only about using math and science to find the truth, but also about much simpler situations, when the truth is obvious. Please let me know if I can help with that in any way.
In the year 2005 I have decided to tell only the truth, today, in year 2015, I am still truthful, it created some problems, but it also helped a lot: reduced fear, gave more confidence, based on knowledge that I do the right thing.
