This has been on my mind a lot lately. Great ideas are only great if you follow through on the original idea all the way through the design phase: design, creation, implementation, feedback, repeat. If you fail on one of these steps, the idea has an increased possibility of failure.
The same is true with our classroom. How often as teachers do we say that we will get the test, paper, or project graded over the weekend so that we can maximize the relevance of feedback we give students, only to have life get in the way. Before we know it, a few weeks have gone by and we're rushing to return one set of assessments to students before giving them the next. In a case like this (which I was often guilty of), we let our students down. The blame is ours to bear when students don't care to revise and improve if the window has passed.
When choosing friends, mentors, and leaders, this is just as important. Choose those who do what they say they're going to when they say they're going to do it. Also, be that person. If you say that you'll find time to research a problem, make the time. If you tell someone that you'll arrange a time to meet with them to discuss a concern they have, check your calendar and make the appointment. If it's just that you're looking forward to seeing someone outside of school, make it happen. Be the person that others can count on to follow through on what you say. That's what our students of ALL ages need. Strong relationships in and out of the classroom make us better educators, but it takes effort and nourishment. Surround yourself with those who are also willing to do the work.
