Is failure the best teacher sometimes?

Yes it is.

Idk if its the best one however it does give you the opportunity to try again.

Yes we learn from our mistakes in life. Failure means you tried and you get another chance to start again, move on or even better depending how much you’ve learned.

Sometimes failure is the key start to your success

Yes but not every time as human when U failed U realise your mistake and U do better the next time

If you don’t Failu you don’t learn.

Failure means you make attempts. So failure is normal.

Of course only when you learn from your mistake

Experience is the best teacher, not failure

Yes failure is always the best teacher, better than any advice anybody could give you. Sometimes we don’t learn from our mistakes as humans, but that’s normal. Keep repeating the same mistakes over and over and over is not normal after you learn them already, but it happens. Failure is how you learn; failure is part of success. You have to fail at something to becoming better at it, because we dont know everything as humans. There no success story in life without failure. Its a journey !

Yes, because it teaches and exposes one to a new and different perspective(s) of life

Is not.

However, it helps one learn faster!

Yes not even sometimes as humans we need to failed early in other to make it out. From failure u can actualised early.
