I had a wake up call a few years ago - made some life changes and ditched my high paid job to work longer hours for less money doing something I feel passionate about and alongside honourable people.
Best move I ever made. Funnily enough despite the fact I now work more, and therefore technically have less free time, I seem to do a lot more socialising, training, and playing of sport and am far happier.
We can always try harder at everything, but it is important to be happy above all. This is not a rehearsal.
