I love how I am too humble to make a list of how awesome I am. Okay that was a joke but it does bring up the first real entry – you have a great sense of humor. You can see the pun in anything and everything, you can joke about almost anything. Making people (including yourself) laugh is something noble and you have a right to be proud of your talent there.
You're not altogether bad looking, in fact enough people have called you handsome that you can probably believe them. You keep yourself fairly in shape, you're not overweight and your are quite healthy with way below average cholesterol and blood sugar levels, nicely broad shoulders and perfectly defined calf-muscles – all of which is good, but not half as good as the fact that you truly have your own style. You look like yourself, people you've only met once always remember you because you truly stand out in a crowd. Many people would hate that idea, fear it, or worse consider it something bad for others to aspire to – but you have the courage to look the way you want to look – good for you.
You're smart, you really are. You can generally solve a puzzle where others see nothing but a wall. You can make sense of things other people just can't seem to understand. You can find a MacGuyver-style solution to most problems. You're creative and you got a real talent with both words and logic – that's pretty rare seeing as most people get one or the other. You manage to be both a math-geek and an artist, it's not something to be proud off really because the talent was an accident of genetics and you never believed anybody should get credit (or discredit) for their genes, but you worked hard to develop those talents and that is a matter of pride.
You care about people. It's been a genuine burden on you for most of your life but it's never made you falter. Even when in moments of exasperated frustration you may have shouted about how you want to just stop giving a damn - you have never seriously considered doing it. It's a hard life but a worthwhile one.
You dream big and you try to achieve those big, impossible dreams. You are far more afraid of not trying than you are of failure. This has meant that you have often had to deal with disappointment but you've always stoically accepted that as the price of a life worth living. You can take some pride in the fact that you refuse to give up on dreams- even the ones that your rational mind knows will probably never happen.
You're dynamite in bed. Now almost every man on the planet actually tells themselves this – but you aren't, you're quoting. One thing your past lovers all agreed on is that your enormous effort put into their pleasure is far beyond the average, that your willingness to study and read books have given you an in-depth understanding of the human body which you put to very good use. That you are happy to make their fantasies come true with never any judgement just excitement. Your caring nature is as much an attribute of how you are as a lover as it is of how you live every other part of your life.
Chances are nobody else is even going to mention sex in this post in particular and that brings us to the last and most important thing of all. You are truly open-minded. In every sense. You are open to new ideas and you don't hold with concepts like "shame" and "guilt" over human nature. You don't discriminate against anybody and you genuinely judge people only on how they treat others. You are sex-positive and you believe in equality for all, you have had friends from every aspect of the human spectrum. Every race, every sexual orientation (including the rare ones like transexuals) and you've accepted everybody without fear or favor or judgement. You are not afraid to talk about subjects that make others uncomfortable and since you genuinely believe their discomfort to be incredibly harmful to society (and you got the scientific facts to back it up) that too is part of caring for people.
You are by no means perfect. You have many flaws and sometimes, some of them mean that you don't entirely live up to your own ideals, even the things I wrote about here are things you've sometimes failed at – but nobody is perfect. You're still a great guy. You deserve to love and be loved. You deserve happiness – never let anybody tell you otherwise again.
