Time... That is a good one! Taking the effort to step back and put things in perspective, it's a tough lesson, but a worthwhile skill to learn!

For me, it really depends on the type of decision. For trivial things, I like to immediately do them... So they aren't hanging around. For larger things, more information is always a good thing!

In a musical setting, I like to lead by example... However, often you do need to take on board the various quirks, preferences and limitations of your musical partners!
