Seldom,
there's a big difference between pushing ones own limits, and even the aircraft's, and BREAKING auth and legal limits.
One can be fun and safe, the other downright inexcusable and dangerous.
For the record I've never knowingly broken an auth and yet I seem to have had plenty of fun whilst developing my own skills to a more than acceptable level.
If this doesn't suit you then you would have no place in a professional aviation command.
