This one is big! I struggled with it for an insanely long period of time. I would love to share how I dealt with it here.

Here's the process in steps:

I) Accept that you are better than others in some areas, and bad in others. Your natural inclinations made you better at some things than most. It maybe because you were drawn to it since when you were very young, and your passion alongwith continual exposure made you learn those things better.

II) The more you start creating success in areas where you are good at, you will start running into people who are jealous of you and intend to create all sorts of troubles for you. It may not always happen, but I suggest that you be prepared to meet this possibility. Rather than deny it and hide from it, you are better off accepting it.

According to my experiences, this is where the fear of success comes from. You are not only afraid of standing out and attracting bad attention, but you don't want to step on any toes.

III) If you focus on the right things, focus on what you want rather than focus on all these stumbling blocks as to why you cannot have what you want, you will find a way to achieve what you want. Nobody can keep dragging you down for an extended period of time if you focus on things that are important to you and have the willingness and persistence to work for it. If others make problems for you, make it a point to face them head on and overcome these problems than give up altogether. Would you rather deal with problems, or would you rather deal with regret of giving up on your goals?

You will always walk away stronger if you take a lesson from your struggles. My experience states that people who seek to create trouble and seek to drag you down will usually attack places where you show signs of weakness or vulnerability. Better then to take it as a challenge to purge these weaknesses.

You will regularly run into competition, which is good. Competition creates a healthy environment and ensures that the most deserving person wins the prize.

If you continue on focusing on all these imaginary scary outcomes that may result due to striving for success, you will find yourself burdened and slowed down.

If people are jealous, it is their problem, not yours. If someone has a problem with you succeeding, it is their burden to carry, not yours. It is usually people who don't have a desire to work hard and accomplish things seek to drag others down. If you let them, they will drag you down. Would you rather share in their mediocrity, or would you rather focus on creating the life you want? That being said, it is very rare that people will physically try and stop you from achieving your goals. Most will try and emotionally drag you down. Learn to thicken your skin a bit. Let their remarks slide off. They are usually taking out their frustrations over you, don't take it personally.

The problem starts when the competition is toxic, and will resort to unfair or harmful means to get an edge.

How to avoid unnecessary conflict and reduce the resistance from others towards achieving success? How to protect yourself from people who seek to tear others down?

Avoid those fields where the competition is toxic, unless you absolutely cannot.

Distance yourself from toxic people in your life who would rather have you stuck in a place they are comfortable with and dislike watching you succeed. This one is most important, and most rewarding.

Stay attuned to others insecurities. Your focus should be on co-existing in a way everyone succeeds rather than on stealing the "pie" from others. Strive to cultivate an environment where everybody wins. You have to learn to create competition with yourself. It's a good idea to show the willingness to help others do better at what you are good at whenever you can. That is how you inspire others to join you and support your goals.

In the long run, you are better off sharing company with those who share an equal passion for creating success or at least seek to be inspired from your achievements.

Despite taking these measures, if others are still creating problems for you, take stern measures. You are being bullied and will need to take strong measures to stop it or prevent it from repeating again. If you display any particular weakness, you become an easy target for bullies. For example, if you are a shy individual, you will regularly run into people who will push you around and seek to take advantage of your shyness. It is your job to become more assertive.

Here's an exercise you can do so you can start focusing on things that matter if you are struggling with fear of success:

Make a list of reasons as to why you absolutely must achieve any of your goals. Ideally, this list must contain your fears (say if your goal is to earn enough money for yourself, what is the fear you associated with not earning enough to support yourself), you current pains (say, your current struggle due to lack of money), and the advantage of achieving your goal (the freedom and relief that comes with earning enough money).

Read this list every day just before you start working. You will soon find yourself more focused on your goals and on doing the right things versus being occupied with the obstacles.
