One of the common reason why we cannot create useful content is because of being lack of knowledge, I know to myself that I am one of them because I am still a beginner of this crypto world and I find so hard to relate myself on some topics here, so one thing that I am doing whenever I don't know the topic is that I use the google search if there is a term that is new for me or I don't understand, it helps a lot, searching before commenting on a certain topic is not that hard and it won't consume so much of you time.
That's true, if we don't have good knowledge about cryptocurrency then it is really hard for us to be a useful member of this forum because in order for us to be useful we should contribute good content here and help other members learn new things.
There are always answers to any problem, you just need to be hard work on finding it. We have the internet that can help us amuch, there are many information that we can learn from searching. If there's a will then there's a way, always keep it in our mind.
That is the spirit, I like the word "if theres a will then theres a way" we can apply it in our daily lives which we should not give up easily because there are always a way for us to achive what we want.
