Bursting your bubble to grow

So we all have our comfort zones.  Shows we like, a spot on the couch, even shitty relationships (more personal).  A lot of times we rather stay in those spots than venture out to the unknown and grow as a person.  This is more obvious at the gym.  For our sport (bodybuilding) so many people have  away they train and don't want to try something new.  Which is why so many people will bust their ass day in day our and not change..or start to look worse.  So I say sometimes we need to burst that safety bubble and try whats on the other side in order to grow as a person and as an athlete.
