There are many possible reasons why someone might see something they like and then not do it. Here are a few possibilities:
Fear of failure. They may be afraid that they will not be able to do it well, or that they will not be successful.
Lack of confidence. They may not believe in themselves or their abilities.
Procrastination. They may put off doing it because they are afraid of failure, or because they are not sure where to start.
Lack of motivation. They may not be motivated to do it because they do not see the point, or because they do not think it is important.
External factors. There may be external factors that prevent them from doing it, such as lack of time, money, or resources.
It is also possible that there is no single reason why someone might see something they like and then not do it. It could be a combination of factors, or it could be something else entirely. If you are struggling with this, it may be helpful to talk to someone you trust about it. They may be able to help you to identify the reasons why you are not doing it, and to develop strategies for overcoming them.
Here are some additional tips for overcoming the hang-up of seeing something you like and then not doing it:
Start small. If you are afraid of failure, start with something small that you know you can do. Once you have successfully completed a small task, you will be more likely to believe in yourself and your abilities.
Break it down into steps. If a task seems daunting, break it down into smaller, more manageable steps. This will make it seem less overwhelming and more achievable.
Find a partner or accountability group. Having someone else to support you and encourage you can make a big difference.
Reward yourself. When you complete a task, reward yourself with something you enjoy. This will help you to stay motivated and on track.
Don't give up. If you fail at something, don't give up. Learn from your mistakes and try again. The more you practice, the better you will become at overcoming your hang-ups. Never be uncoachable!
