Well what can I say?
It is really hard to get things going, one piece of advise, don't try and start a business straight away, it doesn't work.
You need to think about things, and sort of get an idea of what you want to do and do it. Apart form that it's fun having all the new items and stuff.
I must say I did find it quite hard when i first brought the expansion. But when you get used to it it is actually quite fun. You can have a home bussiness including putting up a lemonade stall outside your house or buying a lot which you can make into a salon, restraunt or shops. You can hire and fire employees. If you have quite a slow computor it does take quite a long time to go from your lotted house to the lot where you bussiness is on. Still finding more stuff to do on the expansion and learning new ways to do things. I would recommend, better than pets and university.
