Is perfectionism an issue for you?
You are in this group created by Aaron which makes me think you are analytical and perhaps, therefore, an overthinker, yes? STOP THAT!!
The ADHD brain in me has no filter so allow me to slap you all ha ha.
But seriously, do and do and do again. Each time you will learn something. Especially in these times with tech changing so quickly. You will most likely have to tweak soon anyway. You might as well start practicing now. How may iphone versions have we had now? Hmmm? First iphone wasn't perfect and neither is the latest. Now go.... hop to it.
