I have grown kids and grandkids. I sometimes think my not being here would make much difference. But when they need me or want me I am glad I am here. My youngest son called me at 2am. Who would he have called if I wasn't here? I'm sticking around to be here for them, but I also believe I have a purpose.
Some days are a struggle to get through. Other days are better. I believe each day you wake up is a blessing. I've said on here often: Find a purpose. It doesn't have to be huge. Something as small as smiling at a child can change someone's outlook on their day.
