Learning new concepts can be challenging, and when you face these challenges, it is best to follow this technique - Deliberate practice. This means that you must intently or deliberately practice this challenge, preferably as your first task; This is why it's known as "Eating your frogs first". Combine the Pomodoro Technique, reward yourself, and keep on practicing until you get the hang of it. Remember, "Lady Luck favors the one who tries", so always put your efforts and you shall thrive.
In addition to deliberate practice, when you are learning, make a plan or a schedule. For example, if you write a list of tasks that you wish to complete tomorrow, but the night before, you will be more likely to accomplish the task going in with the plan. Also, plan your commencing time, and as important, your quitting time, which means when you will end. Throughout the period in which you work on your desired tasks, take a few breaks, and make switches from focused to diffuse mode.
