Service-to-Others (STO) means to think about others 50% of the time. Service-to-Self (STS) means to think about the self 95% of the time. To qualify for Service-to-Other orientation, an entity must consider others as often as the self. To qualify for Service-to-Self, the entity must focus on the self 95% of the time, almost exclusively. Where it may seem that these individuals would stand out, some very diplomatic and cultured people are of this category. They are able to disguise their self interest in condescension to others. They are able to disguise their self interest as the interests of the other. During 3rd Density, entities must decide their spiritual orientations─Service-to-Self or Service-to-Others. Most, the vast majority, decide the latter on almost all 3rd Density worlds. This decision, or the lesson of 3rd Density as it is called, needs to precede almost all other lessons, as mixing the two spiritual orientations together creates chaos and thus other lessons cannot proceed. Many entities on Earth are choosing the Service-to-Other orientation, and mid-incarnation are thus joining the ranks of the Service-to-Others.
What is generally considered good most often corresponds to STO. The terms are however laden with a baggage of subjectivity and what is good for one can be bad for another, thus these are easily misleading. The polarization to either STO/STS cannot be reduced to an external code of ethics only.
