I love the original saying about different views on half full\half empty glass.
Here is engineering version of this saying:

For an optimist the glass is half full, for a pessimist it’s half empty, and for an engineer is twice bigger than necessary.

Commas are definitely important. Another good example when commas could change the meaning is defining and non-defining relative clauses.
