Passion. Life is a lot blander without it. Be it work or hobby I’m a big believer that you should do things you’re passionate about. It doesn’t always need to be full on ‘I want to change the world’ passion, but work in particular can be a very dull place if you have no passion at all for the company or the work that you do. Every day becomes an exercise in just getting through rather than feeling excited about what you might achieve.
The same applies to any hobby or sport that you do and perhaps none more so than running. If you don’t have some passion for running and it’s simply something you ‘should’ do then the chances of you doing it regularly and for more than a few months is slim.
