One thing all humans have in common: we like to be encouraged.
When we build others up, we're also building ourselves up. I'm not encouraging false flattery. I'm talking about real, genuine, heartfelt encouragement.
Sometimes, it's simple encouragement from a stranger that keeps me going. We never know what the lady in the grocery store is going through - but it's safe to assume her life isn't easy, either. Build her up.
Always be looking for the good in others, and you'll inevitably find the good in yourself.
