you can teach in a school or even start a baby sitter at home, if this interests you.
someone was talking about lack of quality baby sitters in bangalore. if you are in a metro then you can definitely do this. this should be satisfying and fun as well.

instead of teaching why don't you yourself become student. if not regular degree education you can enroll yourself for many certification courses. it can be about personal finance management, accounting, language, or even parenting. later if needed you can take professional career in any of these area.

If you are interested in some art and craft you can keep yourself busy with that. And decorate your home. Infact a friend of mine is good at embroidery so she keeps making things for her home and she does do some stuff for neighbors for some money. This way she is able to earn some money.

you can also get involved in some social work. it can be as simple as educating children in some of the less privileged areas.
you don't have to teach subjects like physics or chemistry. You can take few sessions and guide them on what they should study, why should they study and encourage them to study. many of these kids think that education is not meant for them or they are not meant for education.

how about helping parents with birthday parties for children. you don't have to do much on your own.
Have some contact numbers ready for each item. like few contact numbers for getting cake, for venue, decoration, etc.
as soon as someone calls you you throw up all the options and based on request you let you contact diary do the work for you. all you have to do is put everything in place. this will be fun and something that many parents over here on babymomstreet will love you for
