This one is very hard for me, personally, because I was brought up to believe that love was the stuff you see in the Spanish novelas on TV. Sadly enough, I can mention at least 4 of my friends who would still hold that to be true. It took me nearly 20 years to realize that love has little to do with passion and lolligagging, and more to do with altruism, patience, support, and acceptance.
It was right there when I also sadly discovered that not everybody has the capacity to feel those things. Very few people are altruistic AND patient, and all the other stuff altogether. As a result, love is also very lonely emotion: it takes a lot of searching to find someone that would reunite all the qualities that are required. However, where there is love for others, there should also be love for oneself. Hence, however hard it is to find someone who knows what love is, as long as you love yourself nothing will bother you. Your time will come.
