A great advice is pointed out here.
Living within your reach.
I so much respect those who live this life because they don't end up pleasing you, before it'll result to living a fake life.

Also, you said one striking thing:

...happiness does not depend on what kind of clothes you wear.

Yay!!
This is definitely true. Clothes will come and go, new fashions keep coming. So there's no need killing yourself now.
Certainly, one step at a time, we'll definitely get there. And we may be surprise that the clothes we were chasing then will end up being out of date in the next few years to come LoL.

Thank you very much for sharing this thought.
