This may be more than one tip, but you only need one “next” step. I work with helping people get UNstuck, and it always surprises me that sometimes business owners are simply overwhelmed, and so they become stuck. If you just choose the next step, it keeps you focused and keeps you productive.
The other side of the coin in this is to always know your objective. If you don’t even know your objective, no wonder you’re stuck instead of being productive!
