I think it's universal that when you witness the break of dawn it gives you that feeling of hope. That assurance that the day is brand new and it signals for you to start new things. No matter how low and sad you are at this point the brand new day is up and so should you. Get up stand and grind.
I love waking up early and witness the daybreaks because of this feeling. You don't need to be with anyone, you don't need conversations. Just the sight of the sun slowly rising and the feel of its warmth on your skin reminds you how great it is to be here, to have this life. It's like it is telling you that you have a reason to be here, fire up and do it!
