Welcome to the board.
As far as being "lazy" now, I imagine that will pass. What you need to realize is now that you have freedom and time, the world awaits!
Go out and enjoy yourself. If you enjoy your job, realize that now you can utilize your full potential, because the end is not coming right around the corner.
Plan for the future. Savor every day, but don't become lazy. Be excited! This can be the best part of your life!!
