I am happy now and in all future moments.

Think of what you were worried about ten years ago this month. Most people cannot retrieve it, and when they can, it usually resolved in some way nobody predicted at the time.

The future is being handled by somebody with more information than you have — a version of you who will have lived through everything between now and then, and adapted accordingly.

That person does not need today's you solving their problems in advance. They would rather you enjoyed the afternoon.

Now is the only moment anyone can be happy in. The others will arrive as their own now, one at a time.
