Getting motivated is the easy part. Staying motivated is more difficult.
This piece from Dr Michelle Cleere shares some insights into motivation and how to keep it running. Here's a short excerpt that we found really thought-provoking:
There are some situations where someone can start off using external motivation that then leads into being engaged and developing internal motivation. This transition rarely happens. When you are younger it feels so much easier to do something for someone but as you grow older, the luster wears off and you are left spinning your wheels trying to meet external expectations.
