Just remember, whatever you decide about your long-term goals, the span of time is a choice you can make. Life happens and it can spoil a life you were satisfied with. From experience living without much application to one’s life, I know how it feels to be trapped by uncertainty to change. However, learning to trust your adaptabilities to those changes will give you things in life that you couldn’t have imagined. You can decide to teach for a few years and when you think you have given all your heart towards the purpose of teaching than I don’t see why it wouldn’t be necessary to move on. Although it’s frightening to seek or make changes in life, realistically the challenges are worth time and effort to make them; imagine how good it’s going to be to start now and not holding yourself down! Tracking or writing your progression down might help. Jerry Seinfeld writes one chain to mark what he wanted to achieve for the day so if he breaks the chain he will know. My heart goes out to you to find what you feel that lays closest to your heart 🙂 GOOD LUCK! 🙂
