Most of us have a second gear for work that doesn't feel like ours. The last task before leaving a job. The favour we didn't want to do. The chore nobody will check. It gets done, but our heart isn't in it, and a corner or two gets cut.
The course tells an old story about this. A carpenter, ready to retire, agrees to build one last house for his employer. His heart isn't in it, so he rushes and uses cheap materials. When it's finished, the employer hands him the key. The house is a gift. Had he known it was his own, he'd have built it very differently.
The course's point is that actions work like that. What you put in, and the intention behind it, comes back to you: sometimes quickly, sometimes much later, the way some seeds fruit in a season and others take years. The course goes further: it says some returns could even come in a future birth. The hard part is that the return is out of sight when you choose, so the shortcut feels free. Most days you're building something you'll end up living in.
