People act like they're having successful business.

In business there are many thing come from the outside, usually those thing aren't in your plan. Like, what if someone destroy your business, what if someone is washing other people brain to not use your product/service etc.
How to solve that? that depends on case by case, usually you know the solution after you're experienced in business.
Business is about adaptation, not preparation.
For this reason, it's never advisable to venture into areas where you don't have the necessary experience and skills to manage and navigate with their complexities. Even in the cryptocurrency space, investing isn't as easy as some might think, as it requires technical knowledge and minimal experience in asset management and network security, and, most importantly, understanding the differences between different networks on the nlockchain.
Exactly, venturing to something that you don't have any idea is something like throwing punches into the wind, there's no clear directions and just hoping that luck will bring something decent to attain success, it's better and always be a must to have that knowledge and skills before entering into any investment or business that you plan to have, it saves your butt in losing and wasting your resources.
You are correct, most of the time, when we take a fancy to do something that holds to be a good idea, we underrate what it means to do so when it comes to preparing. Wishing luck without a logical reasoning is shooting in the dark with the hope of reaching the target. But we realize that things are not always like that. Business and investing are not a game of chance. Not knowing how to read them can be opening the doors to errors that can prove to be costly other than money wise.
I think that there are so many who have a lot to offer but since they do not take their time to examine the ground that is ahead of them, they are overwhelmed. When we are able to sit down, learn, ask questions and build a correct comprehension, everything will go forward with a lot more direction. We are obliged to begin to have sight of knowledge no more as a load, but as an armor. Without that we just have to hope that the weather will be all right during that storm. And that, you see, is rather unsafe to get into the habit of.
