Life is quite easy and simple. Anything that you want to learn becomes easy only when you start developing interest and love towards it. You can start loving about anything only when you have a clear and deep knowledge about it. Our fears stop us from pursuing the things which we want to do in our life. The seed of all fears is ignorance or lack of understanding things as they are. Any subject as a whole looks big, but if you start dividing it into small modules and if you can give your selves sufficient time to be thorough with every module. Over a period of time, you will definitely finish the entire subject. No project is done at once. Every project is broken down into small doable mini-projects, and every mini-project is further systematically made into tiny modules. So every time you work on one small module, you don't have to see how much is still left out. Instead, focus entirely on the tiny module that you are working on. Keep motivating yourselves that a module has been done than worrying on the things to be completed. Your work will be done smoothly only when you have uninterrupted passion, dedication and discipline towards the work that you are doing. Don't Develop an interest or hobby so that you can make money or you get some benefits out of it. If that is the case, the engine will run out of fuel over some time. If you keep doing things without expecting anything in return, the work becomes awesome, and you keep getting things multi-folded, which you never wished for. This is one of the laws of the universe. Your interest in something will not be stopped by any external means. It just goes on.
