life question

[Blender]

I'm one of the younger guys on here at 29, but ill share my path so far. As a kid I was always taking things apart and playing with legos. My parents made it easy to go to college, so I did. I was unsure if I picked the right major, but as I progressed the classes got more and more interesting. It was pretty hard and I was a mediocre student which made me doubt myself. Now I'm working as a mechanical engineer and well respected at work. I love it. I still play the what if game in my head sometimes. I am unsure which path I should take from here. Nobody really knows what they want to do.
