Often, happiness is simply "what addresses the imbalances in my life right now?"
Today, you're probably busy working a 9-5 (or longer). You spend much of your time overwhelmed by the complexity of your job, delaying gratification and doing things you don't want to do. You're stuck inside all day and working through the nicest months of the year.
In that context, of course all you want to do is sit outside at a beach, play some leisurely videogames, and eat good meals. But that's because your life right now has a distinct absence of downtime, nature, and leisure.
When you are retired, the entire context is different and thus what makes you happy will shift too. Once you no longer have a job, you'll likely find videogames boring and understimulating. When you start taking a walk every day in the woods, you might not crave moving to Hawaii quite as much. And when you have the time to cook and savor meals every evening, eating out loses some of its lustre.
Whenever the situation of your life changes, expect your happiness goals to shift too.
