Endeavors

My grandfather still endeavors to absorb new ideas.

All his endeavors proved unsuccessful.

All his endeavors ended in failure.

He endeavors to attain his goal.

We wish him the best in his future endeavors.

I wish him the very best in his future endeavors.

I wish her the very best in her future endeavors.

We wish him well in his future endeavors.

We wish him all the best of luck in his future endeavors.

I don't feel that my endeavors have been appreciated.
