That has been a favourite verse of mine for many years now, in the OP.
For me, God is always very clear what his way is. And if I don't follow it, he let's me know.
But "Trust" is a big part of it. I think for the first 25 years of my Christian walk, I did not trust God. Because I had such bad experiences with getting hurt when I trusted people. So God showed me he was not "people" and I could trust him, even when things did not seem good.
That was a huge learning curve, something he reminds me of, when I forget.
"Trust in the Lord with all your heart, and lean not to your own understanding,
In all your ways acknowledge him, and he will make straightyour paths." Prov. 3:5-6
I translated it from Hebrew and this was my version. Pretty close to most version!
