Let me phrase it differently; are reliable or unreliable?
To me reliability is next to godliness. By that I mean that if someone tells you that they are going to do something on particular time or day, you can count on them to fulfill their promise to you. I write that because when reliable people promise me something I relax because what they have said they will do has always been fulfilled to the best of their ability.
The question remains; are reliable or unreliable?
If you are not, what is one thing that you can do today to improve your own reliability factor?
