Deadlines are terrible. When in a creative field they force someone into creating something they are not passionate about. This drastically decreases the power and greatness of the creation. For instance, if you would create a video every week, the overall quality would decrease some weeks because you would struggle to find a topic to produce. So, if you are starting a creative endeavour, do yourself a favour, don't commit to a deadline if it is optional and you can still sustain your project.
