Don't be too hard on yourself on the isolating part. Its not exactly your fault. The world is tough for us, and every now and then, a subconscious defense mechanism gets activated in order to protect us from the world. So its perfectly natural in our case. As for the question of potential, there is still plenty of time for that. Tolstoy did once say, the two greatest virtues are patience and time. We just have to dig in, be patient and wait for our time.
