I'm the first to admit that there is too much to know today.
Too many software tricks to cram in. Software updates that come at you too quickly. Changes in tax law you must account for. A client list that needs constant nurturing. The new hot social media platform all the cool kids are talking about. The app that is turning heads. A Kindle full of interesting ebooks, a mailbox full of trades, an RSS feed with 500 updates a day.
Plus a family that wants to say hello on occasion.
Editing the list of demands becomes more important each day. Prioritize, delegate, lean on the specialists in your contact list. Hiring someone to do something in 2 hours that would take you 10 is probably money well spent.
Nothing insightful here- just a reminder that we all have reason to feel overwhelmed, and that it's okay not to know everything. You can't- but be sure to admit it.
