More and more people have websites and some people even have many websites. It is not uncommon for some people to have a dozen websites of their own. I think that it is great that someone has many websites, but it is important to keep some things in mind. Basically, I would recommend not to start too many websites if you do not have time to update them from time to time. There are millions of websites on the Internet, but only those are popular which have interesting content and are regularly updated. That is why it might be better to have less sites, but simply update them more often.
Another question many bloggers keep asking themselves is when to stop blogging. They keep wondering whether they are successful as bloggers or not. They do not know that being a beginner blogger is not always easy. Since people do not know you and your work yet, they do not know if they should keep visiting your blog. You need to prove to them that your blog is worth visiting. This might take you some time, but it can be a rewarding process during which you are going to have a chance to make new friends and learn many interesting facts about blogging and other aspects of life. If you choose to give up on blogging to early, you risk losing all those readers you encouraged to keep visiting your blog.
