I've been feeling a bit nervous about my next decisions in life. How do I know what the right thing to do is?
I know exactly what you mean. It's really tough but when I make decisions I try to stand on them and be willing to pivot if necessary.
I think the right thing to do is, if people around you know what you should be doing or where you should be going, they should tell you plainly. To not do that is providing them plausible deniability if you screw up.
That sounds right to me. I actually have a few people around me that give me straight forward advice like that.
