There is a reason not to trust your own understanding. Read a little bit more of what you were referring to. Like the entire chapter and see what it's talking about. You can't understand if you take one line out of a letter and try to make a case out of it.
Proverbs 3:1-35 (HCSB)
1 My son, don’t forget my teaching, but let your heart keep my commands;
2 for they will bring you many days, a full life, and well-being.
3 Never let loyalty and faithfulness leave you. Tie them around your neck; write them on the tablet of your heart.
4 Then you will find favor and high regard in the sight of God and man.
5 Trust in the LORD with all your heart, and do not rely on your own understanding;
6 think about Him in all your ways, and He will guide you on the right paths.
7 Don’t consider yourself to be wise; fear the LORD and turn away from evil.
8 This will be healing for your body and strengthening for your bones.
9 Honor the LORD with your possessions and with the first produce of your entire harvest;
10 then your barns will be completely filled, and your vats will overflow with new wine.
11 Do not despise the LORD’s instruction, my son, and do not loathe His discipline;
12 for the LORD disciplines the one He loves, just as a father, the son he delights in.
13 Happy is a man who finds wisdom and who acquires understanding,
14 for she is more profitable than silver, and her revenue is better than gold.
15 She is more precious than jewels; nothing you desire compares with her.
16 Long life is in her right hand; in her left, riches and honor.
17 Her ways are pleasant, and all her paths, peaceful.
18 She is a tree of life to those who embrace her, and those who hold on to her are happy.
19 The LORD founded the earth by wisdom and established the heavens by understanding.
20 By His knowledge the watery depths broke open, and the clouds dripped with dew.
21 Maintain ⌊your⌋ competence and discretion. My son, don’t lose sight of them.
22 They will be life for you and adornment for your neck.
23 Then you will go safely on your way; your foot will not stumble.
24 When you lie down, you will not be afraid; you will lie down, and your sleep will be pleasant.
25 Don’t fear sudden danger or the ruin of the wicked when it comes,
26 for the LORD will be your confidence and will keep your foot from a snare.
27 When it is in your power, don’t withhold good from the one it belongs to.
28 Don’t say to your neighbor, “Go away! Come back later. I’ll give it tomorrow”—when it is there with you.
29 Don’t plan any harm against your neighbor, for he trusts you and lives near you.
30 Don’t accuse anyone without cause, when he has done you no harm.
31 Don’t envy a violent man or choose any of his ways;
32 for the devious are detestable to the LORD, but He is a friend to the upright.
33 The LORD’s curse is on the household of the wicked, but He blesses the home of the righteous;
34 He mocks those who mock, but gives grace to the humble.
35 The wise will inherit honor, but He holds up fools to dishonor.
Now, you can spout your foolishness if you want. Or, you could read and learn the things that happen when you follow God's instructions and adversely when you refuse to follow God's instructions.
As for why you should not lean on your own understanding. . .
Jeremiah 17:9-11 (GenevaBible)
9 The heart is deceitful and wicked above all things, who can know it?
10 I the Lord search the heart, and try the reins, even to give every man according to his ways, and according to the fruit of his works.
11 As the partridge gathereth the young, which she hath not brought forth: so he that getteth riches, and not by right, shall leave them in the midst of his days, and at his end shall be a fool.
Yeshua/Jesus came to show us how to get it right. He will return to restore ALL things to the way they were meant to be. Folks that hope for and believe that, get it. Those that refuse it, well let's say that they are toast. They have the same choice as every one else.
The side a person choses now determines whether they will be "Smoking or Non-Smoking" . No human was ever meant to go to the smoking section. Only Satan and his followers. But many will chose wrongly and go where they were never meant to be.
