Why do people procrastinate the important things in life? It is because of lack of inspiring goals which leads to indecisiveness.
When you have clear, well-defined and uplifting goals you become decisive and are able to overcome procrastination.
Sometimes, people procrastinate even after having clear goals. In this case the issue could be not defining small steps leading toward accomplishing your goals. When the goal is big, getting there can be overwhelming. However, if you define mini steps towards your destination, taking action becomes easier.
On the other hand, if you have a habit to procrastinate the unimportant, you are on the right track!
