The path to success is to take massive, determined action.
When people 'succeed' they tend to party, when they 'fail' they tend to ponder.
Give people more than they expect, and do it cheerfully.
What people CAN do is very different from what they WILL do.
When you feel you have good although incomplete expertise, start trying things. If it's not working, try something else; maintain an experimental mindset.
Our culture teaches us that making significant changes takes a long time and is difficult to do. This is simply NOT true. Change happens in an instant. It is not a process - it is something you do in an instant by simply making a decision.
