I'll hold my hands up. I'm so guilty with this one. Except I tend to see how far I have gone, once it's too late. Once I've given up.
There has been a few times I've wanted to give up on my blog. But I look at how long it's been going, how much I've written, the memories, the photos, and I decide to carry on.
I want to give up Twitter sometimes. But I look at how I started with 0 followers and now have over 2000, which may not sound like many to some but it is to me.
We're told to not look back, just look forward, but in this case looking back gives us the encouragement and the push to carry on. To continue and to make the hard work worth it.
