Thanks for the feedback. Yes, it is normal  and I also understand but when thinking about it, I wonder what is holding me back from progressing?

Amedion, sorry I just talk your profile and check your topics, https://forum.lowyat.net/index.php?showtopic=3098833&hl= this for example, I once went to gym back in 2011 but stop going after 2 months because I feel inferior with other gym goers around me. I know they didn't even think about me but it's me who feel that way.

I would suggest do a PI test and find out your personality types  and work on those strenghts there will always be introverts and extroverts ..

following this thread as im an in a similar dillema year of the pig !!

I see myself the same way several years back. Don't be surprised that a lot of people are more introverted than they seem. It's work requirement for some people to appear more outgoing but really, they could be more passive than others see them as they are. Almost nobody would believe I'm actually quite the introvert. Work and social environment has 'forced' me to get out of the comfort zone and adapt.

Seems like what you're facing is more on anxiety issues if you're worried about things going downsouth. It's normal to worry about interviews because we tend to feel discomfort about the 'unknown' and especially when something isn't within our control. Recall what a senior of mine said long ago (and it helps):

Look at it this way. If you're not worried about something - it means you didn't care much for it. If you're worried (despite being well prepared), then it shows you care about the things you do.

Conclusion: do your due diligence at work and try to relax. Tackle things as they come

One more, you don't have to compare yourself with others. Are you content with your life now? Or you're seeking changes? What you 'see' on social media may not be the reflection of reality. People rarely share the struggle and harsh reality of life, and only display the rosy part of them.

Sharing 1 example of someone i personally know. On this person's social media is the glam life of flying, hotel stays, holidays and everything colourful. Behind this person's life is a lot of credit card debt, sleepless nights and depression - that most people don't know of.

Really now, if social media is part of the reason, consider doing 'social distancing' from it (pun intended ha!).
There's no need to feel inferior. Everyone starts somewhere. Just ignore the toxic ones and try getting to know some good folks at the gym.
Yes huhu in the gym it's most MYOB unless someone asks. Not everyone welcome advice or correction.

Honestly social media is such a headache so I've mostly cut down. Rarely check it, only when friends tag me, will receive notification and respond. Or occasionally when needed to ask opinion about something/ check news on pages followed. Otherwise just find that it doesn't add value. Having 1-on-1 conversation with others via WA or messenger gives a better connection imo.
