Our life consists of thousands of possibilities and choices - of thousands of doors that we decide whether to open or not. We have already used some and left them in the past, locking the door behind them. We would like to change some, but time has already passed and the key is lost. And some have just appeared before us... Sometimes we do not dare to open them, perhaps for fear of stepping on the same rake from the past, perhaps for fear that the world to which we are accustomed will change a little or collapse completely. But is this fear worth losing what is hidden behind these doors?
