Just got approved for 3 weeks paternity leave and I'm emotional about it

Worked for a year to set this up with my company and finally got the green light for 3 full weeks when the baby comes in July. I know a lot of guys don't get this chance and I'm just grateful. My boss has been supportive which helps. Really want to be there for my wife and bond with the baby during those critical first weeks. Anyone else taken extended leave? Any advice?
