Working on a variety of simple and complex problems is the best way to develop self-confidence in a field similar to Data Science. Your goal should be to give them your all in order to complete them successfully. No matter how eager you are to learn Data Science, repeated failure and failed attempts at computation of a specific task will lead to demotivation and, eventually, a lack of confidence. To avoid this situation, it is critical to focus on one task at a time and complete it within the time frame specified. Begin with a simple programming task or Data Science project that you are confident you can complete. If you're repeatedly failing at a particular problem, don't waste your time with multiple repetitions. It's probably a better idea to move on and consider the other questions that you can potentially solve without the need for outside assistance in that same time frame. Furthermore, if you are able to study, analyze, and research a specific topic extensively, you will ultimately have more self-confidence when approaching the problem. This is due to your intuitive understanding of the concepts, as well as your clear and in-depth understanding of solving the task at hand.
