Balance is a myth!
I do, however, advocate for seasons. In one season, it is opportune to plant and in another to reap. The idea of balance gives me the impression that as one sows, they reap simultaneously and that simply does not make sense—growth takes time.
There is a time and a season for everything (Ecclesiastes 3:1-8). The key is to make the best use of the time in the season that you find yourself in.
