We can talk about what motivation is and how it'll affect us. But, have ever really felt motivation? Usually, it comes by itself voluntarily and we can't really tell ourselves how to get motivated. So, is all we can do is sit on our seat and hope for motivation to come? I for one would surely hate this as I don't think hoping is good enough - I believe working for a miracle is better than hoping for it. In this case, working to get motivated is better than hoping we will get motivated somehow at some point.
One thing about motivation is optimism. Motivation will just not work if your brain is filled with negative thoughts. In my view, optimism is like the energy that pushes motivation and motivation is the energy that pushes one to success. Hence, the reason why you need to stay positive - without it, you will not build that 'force' to success. If you keep on telling yourself that you're a failure, you'll eventually just give up and will not be willing to fight your way through the struggles. But, if you say you can do something, you will be more determined to see it happening, meaning you would go through the challenges on your way.
Doing something only when you feel like it, is not going to help! Trust me, I've done it all the time and am regretting it. In doing something, we need to be as consistent as possible. This is so that we can train ourselves to get used to work and not getting tired every time we try to get serious with some work. Imagine a field, if we've watered them for a whole day, would it mean it doesn't need any more water for the rest of the year? The same goes with motivation - to stay motivated, consistency is key.
Being a hardworking person is not hard - all it needs is focus and dedication. How hard can that be, right? If you give yourself even a single chance of saying "I cannot be bothered to do this!" - you'll find laziness attractive until when you really need motivation - you'll find it's buried in the deep blue sea. Now, how sad will that be?
