Falling in love with an idea plus ignoring reality is the surest road to hubris and failure. Be religious about results, customer value, profitability and employee welfare, not ideas. Ideas are a dime a dozen; executing and pivoting into what works too often is stymied by ego and thousands of other self-destructive tendencies that increase the likelihood failure in millions of ways. There are very few ways to succeed, with a little help from happy accidents and flexible resilience under pressure.
