Today I have 2 quotes for you that go hand in hand, the first is from the movie "Pirates of the Caribbean" and is :
"Take what you can, give nothing back!"
The second is from Steve Jobs:
"Why join the Navy if you can be a pirate"
Both these quotes pertain to the business world in the fact that you will always have competition willing to undercut your prices and outwork you to steal your clients. Remain vigilant and provide a quality service at a fair price to combat this and when necessary become the pirate.
