Strategy
From lvl 1-15 , just do the highest rewarding mission you can. Do note how efficient the energy you'll use. Then after lvl 15 since ego is now a thing, just do music lessons to reach lvl 30 faster. Maybe do some long sb missions before you sleep :)

Sb farm + xp farm are found in zone 2 which is shopping mall rotation. So, just save up for now to buy a pizza box and a pizza slice then a couple of instruments on the way. This way, you'll have 0% ego while doing the shopping mall rotation until you reach lvl 50 :D
