Regarding these physical improvements I would like to add that my experience is that these things don't matter one bit!
I've recently (about 2 years ago) lost 30kg, you would think it'd matter how people treat you, right? NO! No change at all, only compliments, but no difference in contacts.
I changed my hairstyle from VERY short to semi-long/long. Difference in contact? None whatsoever!
I had to wear glasses non-stop for about 16 years (and I couldn't have lenses). So last year I had my eye lasering, no more glasses. Difference in contacts? Even some of the closest people didn't notice I didn't wear any!
So I pretty much changed everything physically on me. Probably the only thing I didn't do was a gender change (and I even considered that
). The only thing I noticed made a difference was how I was towards people myself. What my attitude was and how I made the contact.
Ofcourse this is such a cliché, "it's about the inner you, not the outer!". But one who takes care of himself physically, making sure he smells right, and looks proper has done enough. The rest is up to the way he behaves and thinks of himself. The inner work is way more important to the outer!
And for the sake of variety, let's not all trim our hair to an inch!
