1) In business affairs, do not overstep your needs.

2)Too much business steals attention from the studio.
To spread yourself too thin causes bad relations.

3) Good business relationships are built slowly upon a foundation of honesty and trust..
Do not be overy impatient or ambitious in expansion,
but be determined in achieving the support of your household
as any workman would.
Do not take advantage of others 
nor allow others to take unfair advantage of you. 

4) When you have pushed business and prices to the limit
you have become a greedy business man instead of an artist, 
then your true success has been lost.
