[MCU Doctor Strange/Infinity War] The Ancient One and using the time stone to look into the future

In Doctor Strange, the ancient one comments that she looked into the future but could never see past the moment of her death.

Was this an ego/will power thing, or a limit on the time stone? 

If the latter, when Doctor Strange is looking for ways to beat Thanos in IW, can he only see the Avengers winning if he was still alive when it happened?

The easiest explanation is that the Time Stone doesn't allow you to look any further forward than you would naturally be able to experience. Since Strange was able to see futures beyond his own Snappening, he knew he would somehow be brought back.
