do what you like or like what you do
It shows the importance of a person’s interest. We always wish to do the work which we like. We must always do the things, work, job, etc, which we like doing. We can do great accomplishments in the field of our interest.
But, it is not always possible in different spheres of life that we have the option to do the things we like. Circumstances and conditions may be such that we are forced to take up the things that we do not like to do. So, when such a thing happens we have to like the work we have to do or assigned to us.
For example, we must take up our career in the field we like. But, if we are not able to take up that career, we must like the field we have to enter otherwise.
