AN -ING FORM CAN BE A REDUCED RELATIVE CLAUSE.
There are some people digging for clams.
I've got so many things going on in my life.
My happiest moments were playing on this beach.
I was sitting there, thinking.
Being successful is good.
AN -ING FORM CAN COME BEFORE OR AFTER BE. IT CAN BE THE SUBJECT OR OBJECT OF A VERB.
AN -ING FORM CAN DESCRIBE ONE EVENT THAT HAPPENS AT THE SAME TIME AS ANOTHER. NOTICE THE COMMAS.
Being successful feels good.
We'd run around, playing in the sand, not caring...
I remember sitting outside.
