Motivation is what drives people to do things. People go to work for a paycheck. People workout to be healthier and look great. I can go on and on. But, are your employees (or yourself) really motivated when it comes to work? When you delegate a task for someone make sure you explain why it needs to be done and what your expectations are. Otherwise, it is just another task that isn't important and a non-essential part of achieving a paycheck.
You also want to talk about consequences before assigning a task to anyone, including yourself. Write down three bullet points that will be the result of what happens when the task isn't completed or ins't completed accurately. Being able to look at these bullet points will put the task at hand into perspective and provide real life outcomes for what happens when it is or isn't completed.
Keeping yourself and employees motivated and accountable isn't easy, but it has to be done in order for success to become a factor in your life or your work environment.
