We spend so much time worrying about what others think, Almost every decision that we make is guided by that.
What will my mom think?
What will grandma think?
What about my friends?
Peers, Coworkers? Strangers?
Have you seen those funny videos online of others playing pranks on strangers? It takes a lot of confidence to do that.
They don't care what others think.
You WILL get rejected sometimes, That's just how life is.

It Won't Matter In 5,10 Years.

When you embarrass yourself. It sucks bad. But nothing sucks more than all those opportunities you passed up because you were too concerned about the thoughts of others.
Those days where you didn't get what you wanted because you thought you'd be judged.
Most the time, People won't even remember the event. I realize that a lot now. People forget.
Or heck, If they didn't forget, Then laugh about it!
Most of the time people encourage you to do what is in THERE best interest rather than yours. When you go along with it, You may be passing up the opportunity of a lifetime. And in 5 - 10 years you may realize that you missed out on something that could have gotten you closer to your dreams.

Some People Don't Want You Successful

I hate to say it like this, But a lot of people are Haters.
They don't want to see you successful Or get what you want out of life Because their life sucks. They may quietly throw insults at you, Or find ways to sabotage your ability to get there.
This is a big reason why it's important to cut out those toxic people. But sometimes we may not even realize these people are toxic.

Trust Your Gut

Sometimes we know. We know without knowing that we know. It's the most bizarre thing ever at times When we have a gut feeling about something, and it somehow pans out how we predicted.
Sometimes people will tell you to know, Or they will encourage you not to do something, But you should do it anyways. Sometimes that's the right pathway to take.

Conclusion

People will ultimately pick whats best for themselves, Not you. When making decisions. And you should stop caring about what other people think Because it's just going to leave you without what you want.
So take that risk, Embarrass Yourself. It will pay off!
