If you ever need a little love, to feel important, or that what do you really matters, I know what to do. It sounds a little extreme. First, become a first grade teacher--wait! Don't stop reading...really.
Ok, so become a first grade teacher (stay with me here). Spend over 100 days with your kids, reading and writing and exploring and doing math; some of it will be fun, and some of it will be...well, a challenge. Then get sick--don't worry, with a room full of 6 and 7 year olds coughing on you and handing you damp bits of things all day, that part won't be hard.
Stay home sick for 4 days plus the weekend. Yes, I know the sub plans are killer and the room will likely be a mite messy when you return. Do it anyway. Then come back to school on Monday morning. Stand in your doorway as the kids enter the building. Brace yourself.
They will see you from down the hall. Their eyes will light up and they'll begin to walk faster--not fast enough to get in trouble for running, but fast. As they reach the door, they'll fling themselves at you, wrap their arms around you and hold on for dear life. "You came back!" they'll exclaim, "you're here!" One after another, it happens.
If that doesn't make you feel loved or needed or that what you do is important, then you just aren't trying.
