All managers struggle with the fine balance between doing work that achieves short term goals vs investing time in activities with long term benefits. Output that's immediately visible may give a feeling of satisfaction in the moment, but it soon fades away and demands more energy to keep up with the pace of growth and scale of the company. Focussing too much on progress in the short term eventually slows down every manager in the long run.
Energy spent in growing business may help you achieve some outcomes, but the same energy invested in growing people can produce remarkable results.
