Why change if things seem to be working well?
At some point the opponent will figure out the strategy or there will be an unforeseen threat that is responsible for a setback.
Regardless if the threat is recognized or not, we should consistently pursue change for the better and which usually means it will be worse before it is enhanced.
Our personal development relies on the influential changes that make us uncomfortable. The less familiar we are with a particular adjustment the greater the chance a new learning process will begin.
Our drive will seek the necessary changes to reach new heights. Our mental, emotional and physical strength will always be tested when there is a modification.
If there is a belief that change is necessary, the early pains must be overcome.
Yours in soccer,
