Why do i always have a lot of motivation to do something but half way through i loose all of it? And if i manage to power through it always fails. no matter how hard i try

There could be several reasons why you lose motivation halfway through a task. It may be due to burnout or overwhelming feelings of stress or pressure. Additionally, self-doubt or lack of confidence in your abilities can also contribute to losing motivation. It's important to understand that it's okay to take breaks and recharge when needed. It's also important to set realistic goals and expectations for yourself to avoid feeling overwhelmed. If you consistently find that your efforts are not successful, it may be helpful to seek support or guidance from a trusted friend, mentor, or professional to help you navigate your challenges and work towards finding success. Remember, failure is a part of the learning process, and it's important to be kind to yourself and not be too hard on yourself when things don't go as planned.
