When one-on-one help is worth asking for
One-on-one time is valuable, but only when you use it for the right thing. It's not the place for a general "teach me everything about this tool" request — that wastes the most useful part of it, which is focused attention on your exact situation.
Save one-on-one time for the one specific, nameable spot where you're stuck: a particular error, a particular decision you can't make, a particular piece of your own project that isn't behaving the way you expected. That focus is what makes the time worth far more than a group setting could offer for that exact problem.
Try this today: before you book or ask for one-on-one help, write down the single specific thing you want to leave that conversation understanding. If you can't narrow it to one thing, you're not ready for one-on-one time yet — go do more building or ask in a group first.
