I am a writer. Words have meaning. I think the art of writing is knowing how to say what you mean and the ability to mean what you say.
“I wish the best for you, I want you to know that.”
Wishing implies inaction.
Wanting implies action.
To wish someone the best is to stand to one side and take no action to help that person achieve the best. It is often a form of goodbye and implies that the speaker is done with the other person.
“I want you to know that.” To want something implies that the person will take action to get it. In this case, the person wanted the other person to know something, and they took action to make sure it happened.
The recipient now knows that the speaker wishes them the best.
If you switch those two words you get, “I want the best for you, I wish you to know that.”
That statement implies action behind the scenes, the speaker is working to make things better for the other person. It also implies they cannot tell the other person that they are doing this.
This morning I wanted an apple. I went to the fridge and got it. Yesterday, I wished I had some ice cream, but I stayed where I was and did nothing to acheive it. Since I have stopped wishing I could lose weight and have started wanting to be healthier, it was ok to just wish for ice cream.
Changing wish to want is difficult. In a relationship, both people need to want it. If one person is only wishing then, like two people in a boat when only one is actually paddling, the relationship will just go around in circles and never get anywhere.
Changing want to wish is sad and even heart breaking. To go from “I want this to work out” to “I wish it had worked out” implies that someone has given up. And if changing wish to want is difficult, it is even more so when the wish was a want in the first place.
