And, 4000 doesn't necessarily mean you need to go back to the drawing board - especially if you're just starting. However, as hellokitty noted, make sure you're checking the competition correctly. Use something like Traffic Travis, which will analyze the keyword that you wish to rank for, and then rate it from being extremely difficult to rank for to extremely easy to rank for. Ideally, you'll want to go for something that's either easy or extremely easy when just starting out.
