In 1964 Bob Dylan wrote a song with the lyrics:
For the loser now will be later to win
For the times they are a-changin’
These lines come regularly to my mind when I talk to entrepreneurs who are struggling in the market.
As long as you focus on the things which really matter, namely your users and their problems; you allow yourself the flexibility to refocus your efforts based on (new) evidence you gather from your users and you have a stellar team in place — you will be just fine.
The idea of successful companies getting it right on their first try is just not true. Nearly every company which made it fumbled through their early years — progressing through a series of misses and solutions which didn’t really hit the nerve of their users.
For the loser now will be later to win.
