Getting serious?

I said to Morya “we need to get serious about this”, and I immediately felt that the word serious gives me a feeling of heaviness. There is no play any longer when it becomes serious… So what do I change it to? We talked a bit about it and I searched my system to find the language for “when I am committed, focused and feel that it is important and that I want to do it and that I also feel a lightness in doing it”. What word is there to summarize that? A word that does not take away the feeling of joy that I feel inside? It feels like we will have to develop som new language on this journey!
