So many people are overwhelmed with where to start. They want to make a difference, make an impact, live a purposeful life, have a job with meaning, but don't know what step to take next.
Fix your own house.
Fix a leaky faucet.
Fix a crack in the foundation.
Fix your roof.
Fix here. Tweak there.
Once you become more confident with fixing your own house, it won't seem so daunting to extend yourself to others. You'll know where certain mistakes tend to come up, you'll have some experience dealing with problems and have a better idea where to go when you are stuck.
Fix your own house and you will learn how to help others fix theirs.
The same goes with training your own mind.
