These are my 3 keys:
1. Having a motivated team with a clear common goal: I believe that having motivated people around who understand the common goal clearly is one of the key aspects of a successful startup.
2.Unique and impactful idea: Certainly, a unique idea that solves a problem for a large number of people or improves their lives is crucial.
3. Effective execution: Even the most amazing idea, if implemented hastily, poorly, or unclearly, will not yield positive results.
