One thing people should know is we should always be ready and open to learning new things. We can't make money if we're stuck to the same thing while things around us are changing.
Take a business for example. If you have a business and you don't keep yourself updated about the happening in your industry, your business will most likely not grow. You have to be ready to research and learn new things. Even as a person, we should always try to always develop ourselves. We can't be better people if we don't develop ourselves and the only way we can do that is to learn stuff. Don't have a closed mind.
True!
We have to be ready to "learn, relearn and unlearn"
We have to learn in the sense that we have to acquire knowledge all the time before we can be better. We can't be worth more than what we're worth. If someone is seen to be worth more than he's worth then that person is a fraud to an extent. So we have to be ready to learn and broaden our minds.
Sometimes we forget what we learn, maybe because we have not applied them or we didn't learn well or an opportunity didn't come for us to use what we have learned, then we have to relearn. Learn again.
And if you find out that what you learned and believe was wrong, we should be able to unlearn whatever it is. There's no point holding on to it and being adamant.
