Do I need to stick to my businesses longer?

i'm 17 years old and currently run a web design business.My problem is i'll build up a business then get bored with it and move on.Is this a common problem in business? Getting bored over time?The first business I started was a fingersyle guitar website that made around $200 a month basically passively. Eventually i got bored with it and got side tracked and just forgot to renew the domain, lost the whole site.Now I run a web design and adwords business and typically make 2k a month, however i'm starting to get stressed out/bored with it.I'm finding it lonely/boring spending so much time on the computer.I've started flipping items and ebay and am starting to find that more enjoyable going around looking for products to flip however now i'm getting side tracked once again.I put a lot of work into the web design business.Should I stick with one business until it's successful or is it better to find a bunch of different things? via /r/business http://ift.tt/2rylrP8
