There are three realms: Material, Social, and Narrative (the sense of meaning).
When these are going well, enjoy.
Randomly, one or all of these will crash.
If so, rebuild momentum in that realm, and return to enjoying.
Of the three phases, only enjoyment is required.
As in any game of free play, you could reflect back in an evaluative mood, or, accepting that playing the game was its own reward, simply be grateful to have played.
However the mood strikes you at that moment.
No need to stick to a single game.
Consider having a large repertoire of games that are fluidly used and remixed, and never be shy about inventing a new one on the spot!
