"I didn't have enough time" is a widely used (and accepted) phrase.
"I had too much time" isn't.
Even though "I had too much time" is a lot more common than we'd like to admit.
Maybe even more common than "I didn't have enough time"...
This is especially true when it comes to the things that really matter.
The things we never end up doing because we thought that we still had enough time left to do them.
Maybe even too much time...
Until these things, the really important things turn into the things we don't have time for anymore.
Until it hits us and we realize..
"I had too much time"....
