Tuning the radio

I'm not sure how it happened but a couple of weeks ago my radio re-tuned itself. Now I know what you're thinking... Ghosts, right? Maybe... who can be sure? But, my cute little digital companion, full of ideas that amaze and confound me, is not something I need to pay technical attention to. It just works when I switch it on. So I knew that I was going to have to look up how to fix it and it was all going to take time and probably be frustrating. But there was a bigger problem. The digital display that announces the show and the station and the presenter had been fading over time and now I was going to be tuning it without knowing what was happening. Was it on the right band? Should I turn the knob to the left or the right to remain the right signal? There were no numbers or information to guide me. I imagined sitting there and potentially doing this for days. Attempting to tune back in - unsure if anything I was doing was helping or hindering my goal. We all need feedback on what we are doing. To know if our actions are likely to get us closer or further from our goals. What's ONE THING you rely on to stay in tune with yours?
