Being an SDR, especially being new to the game, can get mundane and old really fast if you don't make it exciting and new.
Have fun with it. You'll actually enjoy work and your personality will shine through on your calls making you more human and people will at least listen to you.
In my first SDR roll I started doing my cold calls with different accents. Got a lot of laughs from coworkers, made it new and exciting. But most of all, made me more successful and confident on the phone.
People like talking to people with accents. I found more folks willing to hear what I had to say and consequently, more demos set.
