11. Your Execution Skills are Weak

An idea alone is really worth nothing. The most important thing is its execution. If you are not comfortable making hard decisions, taking risk, and taking full responsibility, you won’t do well in developing your idea into a business.

10. You don’t understand the Resource Requirements

A major resource is cash funding, but other resources, such as industry contacts and access to marketing channels may be more important for certain products. If you have too much cash but don’t know how to manage it wisely, it can be just as upsetting as too little cash. You must not quit your day job until new revenue is flowing.
