There is a boundary to men's passions when they act from feelings; but none when they are under the influence of imagination. – Edmund Burke
In the digital age of the 21st Century, I think that it's quite important to have your own website, whether for business needs or personal use, because this allows you to be in control of your online presence and reputation. With that said, I still think it's important that you decide upon your topic or reason for having your own website, plus in order to maintain the ability to control your online presence you need to be disciplined in posting regularly. Also, I understand that you may want to be more anonymous by refusing to have things such as Facebook, Twitter, Instagram, LinkedIn, etc. but even if you avoid these, your are still going to show up in the background of another person's photo or may be mentioned in a blog or article. Therefore, take control of your online reputation, because this can potentially help you gain employment OR cost you a job!
