Proverbs 27:1 says, Boast not thyself of to morrow; for thou knowest not what a day may bring forth.  We cannot live for tomorrow.  We may have great plans, but we cannot even be certain that we will be alive tomorrow.  Verse two states, Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips.  Some people love to tell everyone how great they are, but we are advised to not do this.  Bragging on one's self is never a characteristic that followers of Christ should have.  Verse three declares, A stone is heavy, and the sand weighty; but a fool’s wrath is heavier than them both.  We can easily see that carrying around sand or a stone would weigh us down.  Just as easily, we should understand that the wrath of a fool will do the same.  When a fool feels threatened, he or she will lash out at those whom he or she feels threatened by.  Verse four says, Wrath is cruel, and anger is outrageous; but who is able to stand before envy?  When people are envious of others, that is when they are the most dangerous.  When driven by envy, people will never be concerned about what is best for the one they are envious of.  Verse five proclaims, Open rebuke is better than secret love.  Matthew Henry says this means that it is better if our friends rebuke our sins publicly than it is for them to remain silent about them out of love.  We should expect our friends to point out our sins out of love and not to just ignore them.  Verse six says, Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.  I believe that this means that when a friend wounds us by pointing out our faults that we know they do so out of love, but enemies will often flatter us even as they seek to harm us.  We should be truthful in our relationships with others, always looking for what is best for them.  Verse seven states, The full soul loatheth an honeycomb; but to the hungry soul every bitter thing is sweet.  I believe this means that someone who has plenty to eat doesn't find even good food particularly appealing, while a hungry person finds almost anything edible to be good.  Verse eight declares, As a bird that wandereth from her nest, so is a man that wandereth from his place.  I don't believe that this means that we are never to leave where we currently live, but that we are to have a safe place to reside.  Matthew Henry says that it means that we are to be satisfied with where God calls us to be.  Paul travelled continually when he was free to do so, but he did so at God's direction.  Verse nine states, Ointment and perfume rejoice the heart: so doth the sweetness of a man’s friend by hearty counsel.  We should value the wise counsel of a friend as much as we do someone who smells nice, which I believe means that we should look beyond just  what is physically appealing and look to what is spiritually good for us.  Verse ten says, Thine own friend, and thy father’s friend, forsake not; neither go into thy brother’s house in the day of thy calamity: for better is a neighbour that is near than a brother far off.  We should be able to rely on our friends who are close to us in times of need or trouble, and they should be able to rely on us as well.  Sometimes, relying on family, especially if we aren't close to them, can create more problems than relying on a friend does, though this should not be true.  Verse eleven declares, My son, be wise, and make my heart glad, that I may answer him that reproacheth me.  We are to be wise, or acknowledge God, the source of all true wisdom.  If we are, then our parents can be glad in their hearts, if they believe in God.  Verse twelve states, A prudent man foreseeth the evil, and hideth himself; but the simple pass on, and are punished.  We should be prudent, or wise, enough to see evil where it exists and avoid it.  I believe that if we are living under the leadership of the Holy Spirit, then we will always be able to see evil wherever it exists.  Verse thirteen proclaims,  Take his garment that is surety for a stranger,  and take a pledge of him for a strange woman.  This is a warning against being reckless in lending to others without security for the loan.  I don't believe this means that we shouldn't help a person in need, but that we shouldn't lend them money for every scheme they have.  Verse fourteen says, He that blesseth his friend with a loud voice, rising early in the morning, it shall be counted a curse to him.  I believe that this means that a person is not to loudly and continually praise someone who has helped him or her.  We should thank them, but we should not continually praise them, especially if we are doing so only in the hope of getting them to do so again.
