I've been very fortunate for the last few decades to have worked in almost all aspects of VO and on-camera.  Much of the time it hardly seems like work.  Until it does.  When it does  I'm thankful for the 10,000 hours I've put in learning the craft.  It's the result of all that work that allows you to make the most of the opportunities.   We live in a digital world full of "tips" and dubious suggestions ("10 Things you should Always /Never Do").  Voiceover is an analog skill;  it's based on a constantly variable set of parameters.  You have to keep learning about them.
