Need new mom advice!

I'm due in a few weeks and plan to breastfeed and pump. I'm taking a class on breastfeeding soon but looking for any helpful advice you ladies have since I am new to this! I'm planning to mostly breastfeed while on maternity leave (10 weeks) but want to pump and build a supply for when I go back to work. Do I exclusively breastfeed for a while until baby and I get the hang of it, and then pump later after a few weeks to build supply for going back to work? Or pump from the beginning? And any other advice appreciated!
