It's an idea put forth by Rachel Hollis, writer of "Girl, Wash Your Face": Pick your boulder. She recently spoke about this to a large group of Christians who are passionate business dreamers, saying:
The boulder is the ONE THING you should focus on for a season. The idea is this: We all do multiple things at the "good" level, but if we put our energy into just one thing, it would be great. Picture yourself throwing a handful of pebbles into a stream. It makes very little impact. But picture throwing a boulder into that stream. There's a ripple effect, and the landscape may even be impacted. It makes much larger movement.
Hollis suggests you take one thing you want to do and push all the others aside for one season. Focus only on getting that done. Back up even more and map out how you want to get there: Are you wanting to write a book? Have you been stuck in research phase and never actually started typing? Maybe you are wanting to open a store but don't know where to start. So you just keep the germ of the idea in your head but never move forward. Put aside the other things in your life (learn to say no, even when it's difficult), and focus on the boulder. Make the waves.
What's your boulder? What is the biggest project you want to start but because of the other little things in your life, you have not? Maybe you want to go back to school but don't have proper childcare. is it possible to get a better job, that leads to better hours, that leads to easier childcare? How far back in the process do you need to go to set yourself up for throwing that boulder?
Write things down. Turn off the devices, get the kids out of the house, put on only music without lyrics and start thinking. Focus. Don't drift: Write it down.
Next season, are you able to leave that boulder, and move a new one? Try not to revert to being a pebble thrower unless all the boulders are in the water.
