Reply to First Live Performance, Any tips?

I been learning the basics Dj techniques for a while and now I'm going to do my very first performance, where I'm having most trouble are in the song transitioning so if you guys can share some tips i would greatly appreciate it.

also i want to ask what effect would be good to be using on the mix i mean I'm not gonna overdo it on effect just to add some creativity to the mix, i will be using traktor pro 2 to do so.Forbes top 13 Electronic Cash
