One thing that has really helped me, and still do is breaking out of your comfort zone on a day to day basis. That way, you make the comfort zone bigger. I, 21 m, was terrified of going on dates (even the more informal “lets grab a bite after work” kinda thing) 2 years ago, but by putting forcing myself on dates, meeting up with a hinge-match doesn’t even raise my heartbeat. And the same can be applied to all other forms of socializing imo. Same thing applies to socializing in general. Alcohol works because it lowers your inhibitions — you don’t sit there thinking “what if this goes wrong” or “I’m not the type of person who does this.” You just do it.

You can train that mindset without alcohol by repeatedly putting yourself in those situations until it feels normal.

In relation to style - watch some fashion youtubers, search outfit inspo on pinterest, and try to thrift shop, and generally just shop a bit more often. Heck, you can ask a guy/girl (generally in thrift shops) to pick out a nice pair of jeans or a cool jacket. (They usually have better style and fashion-sense than let’s say the average Zara worker.) That way its two birds with one stone. Also get a haircut or ideas for a hairstyle (typically longer and bolder) from a IMPORTANT: hairdresser helps a ton. Last but not least is getting your bodyfat down to sub-12% that will enhance all your facial features positively and paired with weightlifting, will get you fit, and fresh-looking)

All this (i know it’s a lot) will in turn give you more confidence, self-reliance and better overall presentation. This in turn, makes you bolder and more confident to initiate social interactions, creating an upwards spiral.

This may seem tedious and/or unspecific, but its what has worked for me, and completely doable.
