I often read Mark Cuban he has some really valuable insights for entrepreneurs.

When you are trying to hit up a potential investor you will only get one shot (if you are lucky enough to get hold of their email address) so make sure its a good approach.

Here is his pithy view on how to get attention and what not to do!

If you are an entrepreneur who is looking for capital and is sending letters or emails of introduction, leave out the Bullshit.  Say who you are. What you have. What makes it different than the competition. What you want to accomplish. How you plan on getting there and how I can help. Everything else will usually hurt more than it will help
