Every action must have a value, or it is useless for human beings. For example, I have interest in DIY for something about computer, such as 8 bit computer making, gpu card making, new openstack deployment and so on. But compyter, GPU card and cloud computing are all been created so many years ago. If you want to create one thing which has been born for many years and has been produced by only those big companys, it can not bring you money and also value for the world. You have so much knowledge, only by converting them to new actions or new things, will it be valuable. So this is about creation, about new value.
Before deciding, think about the value.
