Everybody goes through issues like this you mentioned, just few snap out of it...

The environment we are in has made many of us live in pretence or live to match the calibres of people around them forgetting who they really are...

People tend to intimate you with how they behave, speak and act..

Being shy can make you lose what you deserve, i lost a job because I was shy and nervous, I aas the best amongst the six that came for the job but I wasn't selected because I couldn't express myself..

I did well in the exam and when it was time for me to confront the MD and CEO, I couldn't speak up or sell myself... I regretted that day..

The points you mentioned are great points to deal with, mostly the
Practice confidence and showcase yourself part...

Sometimes I practice how confident I am with my friends with going for any interview or invite, I try to be evaluated first from friends before I go out for any special invite...

I gained a lot of confidence and I was able to showcase my self when I won the presidential post in school... At first I was so shy and always send my vice to stand for me but to an extent, I was being called upon and it happened regularly till I became bold...

Thanks for this post, a lot of people needs to see this, it will really help many...
