I too agree with Andy. Multitasking is a must as it is lifesaver as you always have several thing you will want to accomplish within 24hrs and doing them one at time simply won't cut it. You would never achieve several goals you would want accomplish and multitasking is not only applied to internet marketing but basically your every day affairs. As it applies to marketing you may may have several business to get started which have several requirements to get them up and going such branding, providing traffic, tracking the traffic you are receiving against product performance and this may be happening across several projects online you may happen to get involved. As such to accomplish all this in over a given period, multitasking is a must.
