I would look at all my variables and choose a 
scaling for each of them such that the units
represent roughly comparable magnitudes. 

Roughly speaking, if you can let all variables
have a range between -10 and 10 or -100 and 100,
then you should be fine. Obviously, this is a
very rough rule of thumb, I would for instance
have no problem if some variable range between
0 and 10, or something like that. This rule of 
thumb is only inteded to give a feeling for the 
maginitude I am thinking about.
