A liar gets entangled in his own web of liesTo cover up a lie you one has to tell 100 more lies is so very true. If a person tells lie he/she will have to web many more lies around it and in the end they themselves get entangled in it. On the contrary a person needs to tell only one truth and he/she is set free of all the burden or guilt which one tries to hide with a lie. The only thing needed is courage.
There are many compulsive liers who lie on every little occasion no matter what and who the person they are talking to. Generally a person would lie to hide his own shortcomings or is having some inferiority complex or is having some very bad intentions.
It is very difficult to judge at once but sooner or later the truth reveals itself. So it is better to speak the truth always and live a peaceful and confident life rather than a life of a liar who slowly and steadily get burdened by the web of lies he/she has created and ultimately perishes in oblivion.
