If you think about it, serious bodybuilding is quite a selfish activity and requires a lot of dedication and comittment.
Alot of people around you won't understand this or be able to deal with it.
It's definitely not a balanced lifestyle and can be extreme.
But you got to do what's important for you, at the time.
You have to decide if the sacrifices you make are worth it.
When you get older, you'll probably see things a lot differently to the way you see them now.
A balanced lifestyle is a good lifestyle.
