“I’ll call grandpa this weekend,” said for a year, adds up to zero calls. Call him now.

Intention does not accumulate. Fifty two weekends of meaning to ring somebody produces precisely nothing, because the thing only exists during the five minutes it actually happens. Saying it out loud feels like progress, which is what makes the sentence dangerous. It releases the pressure that would otherwise have got the call made.

Ring him now, or put it in your phone for a specific hour tomorrow. Ten minutes is fine if ten minutes is what you have, since the call does not need to be good. It needs to happen.
