This is the day.

Psalm 40:4 Blessed is that man that maketh the LORD his trust, and respecteth not the proud, nor such as turn aside to lies.

It is wonderful to see the patterns in the Bible sometimes! The theme of being blessed because you trust in the Lord, has run through these passages, and, of course is the first step to leading a blessed life.
In this verse we see some more ingredients to a blessed life. The first mentioned here is not respecting the proud. So many people today are puffed up and boastful about what they have done, or their accomplishments. Sometimes, it is easy to begin to admire or possibly even emulate a proud person because they have a certain position, or are wealthy. Several other places in the Bible we are told that pride is wrong, and that the only One we should be actively involved in advancing is Jesus Christ.
Second, we see here that the blessed person is not to respect someone who tells lies. Many people hate those who lie, and often when giving an excuse for not accepting Christ people will say, "I'm pretty good, at least I don't lie." God says for us to keep clear of those who are given to lying. Perhaps one of the most subtile forms of lying is gossip, for often gossip includes only partial truth molded into a form that sounds true. The Blessed man will endeavour to avoid all types of lying, at all costs.

2 Examples in the Bible of how God dealt with pride and lying.
I. Nebuchadnezzar--King of Babylon--God took this proud man and made him live for seven years like an animal, going on all fours, and eating grass to break his pride. Daniel 4:29-37
II. Annanias and Sapphira--Christians in Acts--God struck this husband and wife dead for lying to Him and the church about money. Acts 5:1-11
