The world is changing. 
Today's successful recipes, might be outdated tomorrow. What business rule or business environment might change? 

Keep your faith in your own hands. 
If you take action today, you avoid someone else takes action in your place later on. You can avoid unwanted things but you have to act now. 

Do not accept the current situation as a fact of live.
The current situation is the result of decisions in the past. Same major ones but mostly a lot of smaller decisions. They were not necessarily wrong at that time but sometimes the "reason why" is gone but the solution, the way of working, is still there. "We do this always like that".

Do not believe your situation is unique. 
There are some specific points in your company, but that should not be a reason to deny change. 

Being able to deal with change smoothly is a matter of training. 
Employees used to successful changes are more resilient. There will be less resistance than if they have been stuck for years  in a certain way of working.

Even the best in class can improve. You can always learn from someone else.  
Two know more than one!
Wheel and hot water are invented already. Just use them!
