Hello (young) loverboy, or girl, so you're not going to quit your job as you read, and you're going to just help out a little and enjoy! Also as you read. Although how are you going to do all that enjoying? By not over thinking it, of course.
I have a young cousin who keeps saying "Don't over think it"; as much as I hate his generation I have to give credit where credit is due. He's spot on. That's one of the best pieces of advice. So let's hash it out some more. TL;DR: Set alarms for work hours, your default mode is play.
Note do in fact THINK it, perhaps even a couple times, but then leave it to intuition. For example, it's gym time, then, unless it's the first time you're going to the gym just grab your gear and start heading that way. Don't feel the weight of the kettlebell. Don't breathe heavy. Don't sweat. You got it. Get going. Focus on the drive. Focus on your energy drink. Gym shortly accomplished.
Have a vague idea. For example, you will have Friday, Saturday, Sunday off for the next two months. Track any hard deadlines (on a calendar, the best tool for not overthinking it duh) but wing the rest of your precious free time. By doing nothing, napping, sleeping, lounging around, working out, self-caring, watching TV, movies, YouTube, spending time with family, friends, significant others, going out for food, a drink or two, brunch, or just coffee, going out for movies, plays, shows, malls, trying being in movies, plays, shows, backlit mall posters, whew, options abound. You might just keep it simple by reading a book, taking a walk, and listening to music or a podcast, if appealing trying sketching, painting, woodworking, sewing, or such. You'll be happy you had fun.
So much to enjoy!
FOR YOUR EYES ONLY: Quickly including some health coaching along with relationship coaching here, set aside about two hours a day of "me" time - one hour to review the day and set up the next one, and one hour to unwind in bed. Go bonkers otherwise.
