Iíve mentioned in most of my previous threads that motivation is the fuel you need to get you going in the right direction. Self-discipline can get you moved, but not always in the right direction.
See, when you force yourself to do your work (with the help of your self-discipline), you are not necessarily effective, in most cases you are not.

For example, letís take 2 cases:

1- You forced yourself to go to gym and spend a full hour there.

2- You are motivated to grow your muscles and look sexier, so you went to gym.

In which case youíll work harder, smarter, and more effective? Definitely the latter.
Now , I will explain to you a trick that Iíve discovered which can help you boost your motivation, so you can work harder, better and more effective.

Before, let me tell you a personal story:
Like 3 years ago, when I was still in high-school, I was one of the laziest students in my class. Why? Simply because I thought I wasnít going to attend college (though I do now), so I had no motivation to get high exams.
One day, we received our math exam marks, and everyone in my class was talking about the exam during the break. When I tried to fit in with the conversion, they kinda ignored me (because of my low mark), so I felt I was underestimated.
Therefore, I felt a shortage in my social needs which I needed to fill. What did I do? I signed up for doing the exam again, and this time I studied like Iíve never studied before. I was amazed on how much Iíve studied, and now I know why.
It was because of the motivational source, the need that I wanted to fulfill.
If you are wondering about the result, I got a full mark
