The Buddha's Noble Eightfold Path is divided into three divisions. Wisdom, Morality (Ethical Conduct) and Concentration. Right Effort is the sixth element of The Noble Eightfold Path and is related to Concentration together with Right Concentration and Right Mindfulness.
Ask yourself what is Right Effort? Is the effort that leads to possession, fame and status the Right Effort? Is your Meditation Practice Right effort if you can't maintain the posture as it is painful? Is it Right effort when you take care of someone merely because you feel obliged to do so?
Right effort should be focused on:
The Buddha Teachings state that there are six roots of mind. Three Wholesome Roots and three Unwholesome roots. Acknowledge the Unwholesome roots greed, hatred and delusion. Do not give them to much attention because things that you Focus on might grow. Keep this in mind when you temporarily pay attention to them for the sake of acknowledgement.
Choose The Middle Way, know your own boundaries. Do not violate them. To learn one may stretch its boundaries, which is Right Effort. However too much pressure leads to stress, which should be prevented, as it creates UnHappiness, no Peace and disPleasure.
