This really is key. If you are serious about multi boxing - try not to add characters or computers as you go - unless you want to PvE or just do it for fun here and there. The best results are obtained by taking your specific goal of what you want to achieve in advance and then tweak along the way. Plan (in depth) first and then execute your plan. Constantly relearning or resetting up new ways of playing will be hard to adjust to and will ensure sub optimal playing or endless frustrations later.

Plus, things can get really expensive and complicated to redesign later.
