Without certainty about the end result - yes. Without certainty about the ratio of danger vs reward of the next step - never.

How do you find that certainty tho
You need to be mindful about every step you make, and the steps must be small enough, so that you would be capable to evaluate exactly what you are risking by taking the step and what is the potential gain from that particular step, and make an informed decision whther that is the step you want to take or look for better alternatives.
In my world bravery = russian roulette = stupidity.
With research, math, and very well studied and decomposed personal priorities, you can go through life with taking only minimal risks.
I understand, and mostly agree. I just have the feeling that such certainty is only an illusion. What we feel as absence of risk or low risk is but a mental construct for us to feel good, so that when everything comes crumblig down we can say "it was one in a million, doc!".
That would indicate too large steps or simply a reckless conduct. Which indeed is a way of life for most people. Nowadays people would be unreasonably fearful most of the time, and after reaching an instinctive end of tolerance of inaction would suddenly act reckless. It is like they hate investing effort in thinking so much, that they would do anything but profound thought. This was true throughout the entire history, just the balance of recklessness and inaction shifted.
The inactivity vs recklessness is very evident in western women. At first they are afraid to stand out, be different, look different, not to have a husband, not to have standard number of children, not to have a standard job, and then at the middle age they "find themselves", divorce, act like teenagers at the age of 50.
