Thanks a lot for the info @holoferncro ! Truth is as I was able to move on the missions list I was doing the next ones as often as I could (until my energy ends), but I started focusing mainly on illegal busking for now!
When I reach level 10 I am thinking of starting the Music Lessons! 🎵🎵🎵
Well it depends on what do you want to achieve. This early on I don't see the value in Music Lessons except for exp but faster leveling means sooner ego meter will come in (on lvl 15).
Right now I'm very competitive in rankings so I try to maximize starbits so I can keep buying packs, which means I'm doing shorter missions a lot per day which gives me a lot of mission ego and still I don't have to do more than 1 Music Lesson to counter that effects.
Also later on game will have some card requirements to progress further so level is not the only factor here. And if you want to buy some cards I recommend using NFTMart because it is easy to use and you don't have to think which offer is the cheapest in the selected currency.
