There is no problem with pairing or with going with extreme programming values. In fact I support the majority of the points in this article. However, the question you need to ask yourself is whether if you believe that it is worth investing all your time on every. single. ticket every day and pairing for meetings and stand-ups every. single. day. for that salary you negotiated (or worse that you took a lower salary for) all for the chance to increase it +10% to show that you are "performing" well for the employee of the month award at the company. How are you going to get that time back? (Remember, you will not get any of it back). Do you really think it is worth missing weekends for this if you are behind on a deadline? Are you really sure?
