Finding the Right Balance After Fajr

Wa alaikum assalam, everyone. As a Muslim living in NYC, I'm trying to get better about my morning routine. I used to head straight back to bed after Fajr prayer, but I know there's blessing in staying active during that early time. These days, I might go for a walk, sometimes get to the gym, or spend time with the Quran. My challenge is that as the seasons change, the Fajr time gets earlier and Isha gets later. With a standard 9-to-5 job, I'm figuring out how to manage enough sleep, fit in some exercise, and still be consistent with all my prayers at their proper times. I admit, I used to pray Fajr whenever I finally woke up, but it never felt right. It felt like I was choosing my own comfort over what Allah (SWT) has asked of us. I also find that taking naps later in the day tends to throw off my whole sleep schedule, so I really try to avoid them. Any advice from others trying to juggle similar commitments?
