you'll go nuts sitting on your ass bro.
and it's not like you got enough disposal income to go travel the world and do crazy shit, like alot of people who retire in their 40's. Most people i know who made it (the only people that actually retire in their 40's), don't even end up fully retired. They just have a bunch of investments and side businesses that are delegated for the most part.
go back to school, or find a new career. something you enjoy
