To look forward to something means to think of a future event with pleasurable anticipation, i.e. you are excited about something that will happen in the future.
I am looking forward to hooking up with some mates who are coming to Málaga at the end of next month. Last night I called them to tell them about my plans for things that we can do in Málaga. Thanks to you, I have lots of activities planned. They will definitely fall in love with Málaga and have a blast.
In general, what do you look forward to? Your birthday, the weekend, Halloween, important football matches, sleep? Generally speaking, I look forward to eating and drinking!!!
