Somewhere in the middle...
Back when I did Triathlons it was important to strike the right balance in training - too little and I wasn’t fit enough to do my best, too much and there was nothing left in the tank come race day (assuming I hadn’t injured myself before then).
Building a business needs balance too - not enough effort and momentum is lost and sales suffer, too much effort and you risk burning out, or doing nothing but flitting from task to task and doing none of them well.
Balance is the key to so many things in life, and sometimes the only way to find it is to have experienced the extremes and know that the sweet spot lies somewhere in the middle…
