To worry about tomorrow is to detract from your work today. Time you spend thinking about tomorrow is time you're not spending thinking about what to do today. The place you leave in the code because you think you'll need it tomorrow, is actually a waste of time today — and a liability tomorrow. It does more harm than good.

Never worry about tomorrow, Charlie Brown. Tomorrow will soon be today, and before you know it, today will be yesterday! I always worry about the day after tomorrow!

Anxiety is fear about what may happen in the future, and it occurs only when the mind is imagining what the future may bring. But when your attention is on the here and now, the actions which need to be done in the present have their best chance of being successfully accomplished, and as a result the future will become the best possible present.

Relax. Your rumination, analysis, worry, and need to control the future are robbing you of the current moment. Yes, there is a time for preparation, but continually thinking of the future guarantees you'll never enjoy the present.

Do not worry about tomorrow, for tomorrow will worry about itself..

You can destroy your now by worrying about tomorrow.

Why should you trouble yourself about the future? You do not even properly know about the present. Take care of the present, the future will take care of itself.

Today is the tommorrow you worried about yesterday.

Remember, today is the tomorrow you worried about yesterday.

It's not helpful if we spend every day dreading tomorrow ~Jai

Anxiety is fear about what may happen in the future, and it occurs only when the mind is imagining what the future may bring.

I-I don't know, uh... I mean, I have a hard time thinking beyond tomorrow.

If I fret over tomorrow, I'll have little joy today.

"I guess it's wrong always to be worrying about tomorrow. Maybe we should think about today..."
"No, that's giving up... I'm still hpoing that yesterday will get better."
