help a beginner dj out!

Hello! i’ve been wanting to progress in my Djing, i’ve been in and out of it for the past few months due to school but my motivation to learn hasn’t change. lately, i’ve been struggling in creating my beginner setlist. i’ve been stuck in a song that i can’t find a match to transition out off. anytips when it comes in creating a set list or finding the right song? thank you in advance!
