what is the best preference

IMHO, you should do both. Internet has many great income opportunities, but it also comes with great risk so do not depend entirely on it. i try to invest my money in internet, and so far i am quite satisfied with the result (although i've had some losses too). but like i said before, dont depend entirely on internet for your income sources.

it depends...if you think that doing some internet jobs and outside work has the same income so better do internet jobs rather than working outside. You can earn money and at the same time you will still spend time with your family.
