to vs toward

[layla0302]

I can't find the difference between to vs toward

Can I put "to" instead of "toward" in the sentence below?

You don't need to thank everyone you've ever met or members of your family that have done nothing toward this.

I don't think so. It's possible, but sounds much less natural.

[Raymott]

It doesn't sound right to me.
