happy: understanding

understanding physical senses
understanding feelings
understanding others' points of view

happy: feelings

Being appreciated by others.
Sensing my own reactions, sometimes.
Joyfully interacting with others, laughing with others (which reminds me I
should go look up the video which starred in an anecdote today).

happy: body

Feeling the stages of recovering from excess effort.
Functioning with less than idea sleep patterns.
Periodically feeling invincible. (Must draw my attention to the recent
past when this occurs... so that I can better evoke this feeling.)

happy: life situation

Confidence that my basic needs will be met.
Pleasure in freedom to do, experience, and choose my own approach.
Comfort from having more things than I need--just in case.

happy: other people

Having friends who teach me.
Having training partners who gladly ensure I repeat my turn until I learn.
Having exposure to friendly (usually smiling) clerks when I go shopping.
