Behind every action, there is always a motivation to get a specific result. When you do every action with an eye on the end result or on any specific goal, the expectation of the result affects the process of your action. But when you perform some actions as an expression of joy and are not bothered about the result, you will not be lost in the means.
When you do some actions expecting joy out of them, it makes the action inferior. For example, you want to spread happiness, but if you are keen on finding out whether the other person has become happy or not, you get entangled in their vicious circle and you lose your happiness in the process. Or suppose, you want to take up a project, but you start it by worrying whether it will happen or not, then your whole enthusiasm for the project gets dampened.
The concern about the outcome of your action is what pulls you down and dampens your enthusiasm. So when you are aware of your potential, just jump into the action you want to do without bothering about the result.
