You don’t have to be upbeat and happy all the time. There are some bad things happening in this world, and they can bring you down. That’s okay, as long as it is a temporary state. You want to be able to bounce back and see that there are still things to be happy about, even if they are small things; small things can grow into larger things when they are nurtured and appreciated. If you are down for a while, do not give up and assume that you will always be there, things will change; they always do.
