Social media is as superficial as it gets, but its perfect for what the threadstarter asks for:
I like to travel. I post some nice pictures when i am on vacation. Additionally i bought an old boat with two other friends. From time to time when sailing or when we have a party on the lake with other boats i post a nice story. Addionally i began photography 3 years ago. I love this hobby. And post some pictures i took, too.
So why is this a good way:
You use your money not on women you are dating, but on yourself and display it on social media. Vacations are expensive, the boat is kind of expensive (but not too much in my constellation), photography is expensive. When women see my insta, they surely think that i am a guy, that they can have fun with (traveling, boating, getting photographed...) and thats creative. Additionally it signals, that i am not poor.
Yes, sometimes if had a good date i pay for drinks or dinner. But to be honest, its not that often.
I normally hate bragging! But creating a good online profile is just important in todays world. I add my insta on my tinder and bumble profile and thats it. Just pay for a good life, learn a new hobby and display it there! Thats what makes you stand out.
