Have you changed since late teens ( college beginning to end)? In what ways did you change?

So for reference I am a 28m. My own experience has been, it’s taken me almost 10 years (shy of 3 months) from first semester to last class, to finish my associates degree (graphic design) a lot of it due to financial or life reasons. But I’m finally finishing. However I am burnt out on graphics now and no longer feel as passionate for it to compensate for the pay if offers at entry level at my age. Tonight I realized how much has changed over the course of that 10 years for me. I started off as a young punk skateboarder who wanted to make art for a living, and now at 28 I realize I’m no longer the person I once was. I’m a bit to old to start off grinding in the graphics field for $12 an hr as a newbie. And I’ve shifted my focus towards military (I’m about to enlist in the army with a Ranger contract because I love the outdoors and guns) I feel like a part of myself is dying with the closing of this chapter and moving to a new one and I am wondering how any of y’all felt over the course of your life’s transition? Looking for some perspective as to how y’all dealt with it I guess. Any comments are appreciated.
