This is saying that it's good to be happy about little things. Every little accomplishment you make is one step closer to what you are trying to achieve. Don't just think because it is something small that it doesn't matter. If your don't celebrate the little things, trying to accomplish your goal will be hard.
again.. you'll find a way to get through this! im not sure what you forgot but i know it will be okay!! somehow someway! take a deep breath and think slowly! and remember this is the same advice you'd give me!
