“Negative thinking will not produce positive changes - ever.”― Taite Adams
If you can't be positive, then at least be quiet.
I don't mean any disrespect by the previous sentence. It's what I have learned on my path. And it really works.
Sometimes you just ain't feelin' it. Sometimes you just ain't having your best day ever. And that's okay. And to be expected sometimes. This is called contrast.
But don't draw everyone around you into your negativity and drama. Just stay quiet and let the storm pass. It will.
