Competition is only bad when you are near a competitor who wants to win or stays in the front, no matter what.
Good and Healthy competition, only make us betters persons and better human beings. That's what I think. We have so many advantages with the healthy competition: friendship, push-ups to the limits, etc.
So yeah, It's like you said, good competitive behavior is important for growth and success too.
Keep the good work dude!
Cheers,
