Congrats. I will say what I've said before, save up for a rainy day fund, mortgage and car down payment. You have money based on your current living situation - but you will need to flock the nest at some point. By all means treat yourself to something to celebrate though.

..that is often the method of reducing staff cost, just own a little army of interns and short time workers ... some companies here do that too, though they suffer also from bad reputation and the scrutiny of the tax office.

If you want to.
