• You feel unworthy because you don't think you're doing enough to improve yourself. Self-improvement should help you to recognise your strengths and work on your weaknesses.
• Unrealistic expectations.
• Unproven claims. There is no scientific method that can test the claims of self-improvement literature.
• Impatience with the amount of information and the supposed improvements you need.
• An oversaturated market of self-help literature. Not everything is beneficial.

With self-improvement content, you can easily think improving yourself means changing into a new and different you.

While desiring to improve is valuable, it is very different from believing you have to become someone you're not to get what you want.
