When you speak, be sure of what you are speaking. Don't be rambling full of words that have no integrity or truth. Nobody wants to confide in you when they doubt what you say. If you are filled with untruths, those characteristics make it hard for anyone to believe in you.
Do not allow another person to set you back. Continue moving forward not backwards. When someone pulls you back, be like the arrow to a bow and spring forth greater than ever. And, what they thought would be your disadvantage, you turn it into your advantage.
Failure is success in abeyance; but only for those who persevere.
