I've noticed many captions and videos have people claiming that others don't want them to take certain actions or succeed in life. People do often have those negative influences in life but avoiding toxic relationships is almost too simple. And I am almost positive that nobody is wishing every day that you don't pass that exam or get that job.
If you are surrounded by those types of people who aren't constantly encouraging you and even help you to achieve your goals in life, then my suggestion is to walk away from those relationships. If those you speak of that "want to see you fail" are people you don't even have a relationship with, then why do their thoughts matter? Why are people so focused on the opinions of those that aren't even present in their day-to-day life?
Achieve your life goals, achieve your daily goals and even achieve your hourly goals of simply keeping it together. The goals you set for yourself are more important than a negative comment from a stranger. Post about every achievement if you want. Keep it to yourself or even just inform close friends of every step you take. It doesn't really matter how loud you are because it's what makes you feel accomplished or just good. Every accomplishment will eventually show in the end result.
Take time to also check your own effect on someone's life. Make sure you aren't a negative person in someone's life also. No decent human wants to see anyone fail in life. Maybe they don't exactly want you to get what they want but nobody truly wakes up every day hoping you don't get that promotion.
Everyone has problems and goals of their own, so continue to enjoy, share and love your accomplishments and life.
