Four Instructions for the Organisation of Your Master Mind Group from Think & Grow Rich Chapter 7: Organised Planning  #TGR

(a) Ally yourself with a group of as many people as you may need for the creation, and carrying out of your plan, or plans for the accumulation of money-making use of the “Master Mind” principle described in a later chapter. (Compliance
with this instruction is absolutely essential. Do not neglect it.)
(b) Before forming your “Master Mind” alliance, decide what advantages, and benefits, you may offer the individual embers of your group, in return for their cooperation. No one will work indefinitely without some form of compensation.
No intelligent person will either request or expect another to work without adequate compensation, although this may not always be in the form of money.
(c) Arrange to meet with the members of your “Master Mind” group at least twice a week, and more often if possible, until you have jointly perfected the necessary plan, or plans for the accumulation of money.
(d) Maintain PERFECT HARMONY between yourself and every member of your “Master Mind” group. If you fail to carry out this instruction to the letter, you may expect to meet with failure. The “Master Mind” principle cannot obtain where PERFECT HARMONY does not prevail.

Even if your goal is not necessarily to make money, I feel like this list is true.
