Got a very cool looking Green Lightning in today's pack and so the guitar lessons are something that I could potentially do in the future although there's no benefits to switch from my usual singing lessons that I am aware of.
For now, I have enough fans but I do look forward to getting character cards more than musical instrument ones. Although getting rare or better Mics would definitely be welcome as well.
Ranking is fairly consistent in the 450 - 460 range and it doesn't seem easy to get into the top 400. Lots of competition and everyone is moving up.
I've brought the ego down to 3% and maybe tomorrow I will do some more music lessons to get it down to 0% or maybe 1%. The challenge is staying up late to do the missions for the night and a music lessons extends it by one hour.
