An interesting article written by Benjamin Wirtz on LinkedIn that talks about how focus is the key to startup success.
While I agree with much of what is said and it is a worthwhile read for all companies, the only point I would like to expand on, not explicitly mentioned is flexibility.
It is very important to stay focused to get the job done, the product developed, the app built, BUT it is just as important to review other ideas critically and regularly and to stop focusing on one particular goal if a new goal proves itself to be better.
So I would talk about Focus and Flexibility adding it is all about validated customer needs, rather than self-generated ideas. Sticking to these principles with just enough luck, should guide your business to success.
