Daniel,
Great self reflection, Daniel. Experience can be a great teacher, but only if we learn from mistakes, adopt a willingness to adapt attitude, and assume our responsibilites seriously with the anticipation of great student outcomes as the result of our efforts. Being real, genuine versions of ourselves rather than an imitation of someone else is also important. With these traits, we can arrive in the classroom competent and confident with ourselves and and the content we're accoutable to teach.
