The First Step is the Hardest?

So today marks the end of my first week of my 'organised' healthier lifestyle. And by that, I mean that I got a reward jar.
I saw a blog post that recommended, for financially minded people, setting yourself a reward system rather than relying on simple motivation to keep you heading towards to your goals. I figured that was pretty much exactly what I needed, so last Saturday I made a short list of things I wanted to turn into habit (going to classes, walking to uni, making healthy lunches) and gave myself a small reward amount for each one.
I really feel like, for me, no motivation is better than knowing I'm saving money and getting healthier too. I really think (hope?) that this might be an idea I actually stick to.
I even went jogging this morning.
I lasted fifteen minutes.
But it was a start.

I don't know if the cliché is true, but I'd like to hope that it will get easier from here.
I don't think it will, but maybe I'll keep going anyway.
