Proverbs 4: 10 - 22 (NKJV)
10 Hear, my son, and receive my sayings,
And the years of your life will be many.
11 I have taught you in the way of wisdom;
I have led you in right paths.
12 When you walk, your steps will not be hindered,
And when you run, you will not stumble.
13 Take firm hold of instruction, do not let go;
Keep her, for she is your life.
14 Do not enter the path of the wicked,
And do not walk in the way of evil.
15 Avoid it, do not travel on it;
Turn away from it and pass on.
16 For they do not sleep unless they have done evil;
And their sleep is taken away unless they make someone fall.
17 For they eat the bread of wickedness,
And drink the wine of violence.
18 But the path of the just is like the shining sun, (literally – light)
That shines ever brighter unto the perfect day.
19 The way of the wicked is like darkness,
They do not know what makes them stumble.
20 My son, give attention to my words;
Incline your ear to my sayings.
21 Do not let them depart from your eyes;
Keep them in the midst of your heart;
22 For they are life to those who find them,
And health to all their flesh.
As you can see, in summary, wise living adds to your life in every way, while we are warned against following the paths of evil for it only brings pain and sorrow in the end.
