Do I really need another domain?

Just because I want to make sure its mine! MINE MINE MINE! and no one will take it…

Whats the point?

When I got this domain I was like 17 or something. It was just the IN thing to do. Now I own 2 domains and I pay $19 a year for them. Error42 and mymomsattic. None of which have made me money as of yet.

Maybe error42 will. Maybe it wont. It’s kinda just a pointless blog. If I pick up another domain, wont it just be another one of those needless things i pay for annually?
