Challenges you face the most as a DJ?

I’ve been getting started as a DJ for about a year now. Aside from the challenges stemming from trying to land gigs, what are some of the more technical challenges you face as a DJ? (i.e., building / curating sets, planning transitions, learning how to do certain techniques etc.).

Just out of my own curiosity - wondering if some other DJs out there face similar / vastly different challenges.

Gladly taking input from any level of experience (recognizing I’m still a noob haha)

Thank you!
