Teaching my boys about keeping your word
Had a situation come up where I promised to help a neighbor fix his fence last Saturday. Weather was terrible and honestly I didn't feel like it. But a man keeps his word or he's worth nothing. Showed up early with my toolbox and we got it done. My oldest watched the whole thing. That's the lesson right there. You're only as good as what you promise.
Teaching them to follow through even when it's inconvenient sets them up for everything. That's the kind of person people actually want to work with later in life.
