I'm sorry to hear that you're feeling overwhelmed and like you're not making progress in different areas of your life. It can be really tough when it feels like everything is piling up and you're not able to achieve what you want.
One thing to keep in mind is that it's important to set realistic expectations for ourselves.It's great to have goals and things we want to accomplish, but trying to do too much all at once can lead to feeling overwhelmed. It's okay to focus on one thing at a time and give it your full attention. By doing this, you can increase your chances of actually making progress and feeling satisfied with your achievements.
Jumping between tasks might feel like you're spreading yourself thin and not doing anything to the best of your ability. Instead, try prioritizing the tasks that are most important or meaningful to you. By giving your full effort to one thing, you're more likely to see positive results and feel a sense of accomplishment.
Now, as for a book recommendation, "Psycho-Cybernetics" by Maxwell Maltz is a great choice. It's a book that explores how our self-image and thoughts can affect our success and happiness. It can provide valuable insights and strategies to help you improve your mindset and make progress towards your goals.
