I personally have never felt entirely comfortable in business unless I'm stressing about something, I think it helps you acheive more (and I'm not knocking those who like to coast - we all run companies to create the lifestyle or income we want), pressing yourself, colleagues, and the business to tight deadlines, setting very ambitious goals creates stress, and I wouldn't have it any other way. It obviously just has to be manageble. I actually don't like it when its all too easy, in those moments I go and do something which I know will pile pressure on. If I don't feel under pressure, my motivation to do anything is quite limited. I am about to invest a lot of money next year that I don't really need to with a mature business like ours, simply because I want the challenge of getting into something else we have little experience in, that potential for failure, that need to get a return on the investment, bring it on!
