What are the examples of micro enterprise businesses?

Very small scale schemes to make a little extra money. These could, of course, expand into a major source of income but if it remains a sole proprietor it could be still classed as micro enterprise.

These could include;

Adolescents mowing lawns, dog walking, babysitting, etc.

Working part time from home or garden.

Private tutoring

(Note; doing these things without advertising or creating opportunities is not enterprise)
