Whether you should implement an idea should depend on whether that idea has the potential to meet what YOUR objectives are. If your goal is wealth creation, you will have to check if the business case is strong and if this is what will create wealth for you. If not, you will evaluate other opportunities.
On the other hand, if your goal is NOT wealth creation but ‘social impact’, then you will evaluate if this idea is providing the scale of impact that you wish to create.
And if your goal is to ‘enjoy what I do’, then you have to evaluate if this idea is what will give you the greatest joy.
If your goal is wealth creation, you will have to evaluate things like what is the scale of the opportunity, what is the competitive environment, why do I have an opportunity to be a dominant player, what is the scale that I can reach with this venture, what are the resources that I will need and can I gather the, what are the competencies that I will need and do I have them or do I have the ability to engage others who have those competencies, what are my exit options, etc.
