You can start anew at any given moment. Life is just the passage of time and it’s up to you to pass it as you please.

If you don't want to start changing yourself, don't wonder why you're miserable

It’s January and I’m kicking snow off the ground. I just threw out the flower you made me promise to water, handle with care, because I was too careless, you said. Careless with things and people, around me and behind
and I remember being still for just a second or two, thinking that it’s so much easier to leave and start anew, than take care of what’s already here.

Now I've gone for too long
Living like I'm not alive
So I'm going to start over tonight
Beginning with you and I

Isn't it nice to think that tomorrow is a new day with no mistakes in it yet?

I keep turning over new leaves, and spoiling them, as I used to spoil my copybooks; and I make so many beginnings there never will be an end. (Jo March)
