Turning a passion into an idea is a great way to startup a business. However, this idea can’t be just a hobby which is not a strategy for success at all!
You must do homework first to add all the needed component to make your idea a successful business. Typically, you will have to do so much analysis and R&D such as understanding your market, knowing your competition, developing product or service value proposition, measuring your costs, go to market plan etc.
Before burning any capital and efforts, you should be able to answer for yourself “what value are you creating for all the stakeholders?”. Remember, you are not the only stakeholder in this startup business, regardless how much equity you have in the company! You have an obligation of creating value for all the stakeholders such as investors, team members, suppliers, landlords, customers, environment, and even for the local, state & federal tax collectors. If you can put yourself in all these perspectives and evaluate a tangible value for all the stakeholders then you have valid business to startup.
Build something significant that it has value to the masses, you will never get tired of doing it.
