I didn't know how to swim when i was born. I doubt if you did either. In-fact I used to be quite afraid of water. It embarrassed me that my friends could just float when I was holding onto the ground beneath for dear life. I always thought I'd learn one day but it took me quite some time to realize that I can't do that sitting inside my safe, comfortable, familiar room. In-fact I can't learn pretty much anything after a point until I let go the familiarity of sameness, the tranquility of repetition and the protection of my parents. To learn I have to explore unfamiliar grounds and dive into that swimming pool. Its new so it'll be scary, uncomfortable and risky. I might tap the water in anxiety, look around for help, gasp for breath and may be I'll never be able to come out but if I do, if I do survive, if I do hang in there then I WILL know how to swim. The time in that unfamiliar terrain will teach me more than any lecture could, any tutorial would. I can always quote from others' experiences but I can learn only from my own.
I have one life so I'd rather say yes than no, I'd rather move ahead than hold onto my past, I'd rather take that chance than look for excuses to maintain the status quo, I'd rather win the world than live a compromise.
