Just play and have fun if your wanting to play out get a gig booked and go for it your going to embarrass yourself anyway the first time or so. Go play for free and let things develop. If you try to practice and become good you will fail instantly because you yourself will never be satisfied with your playing so if you wait til you become satisfied your band will collapse. I am now 62 and every band that I played in that made money and I did make a living doing it learned about 15 songs maybe in 2 to 3 sessions and went out to play. Those bands grew and made money. The bands that worked for 6 hard months never went out to play never got good enough. Plus we threw chairs at each other LOL I know when younger I threw a guitar or two, have fun.
