It's one thing seeing a sword getting sharpened by the blacksmith, and another trying to train your brain into doing things specifically for you. In movies, all swords are perfect. Shields smoothly curved. We are never shown the swords thrown away because they were too thin. The shields still at work because it's not smooth.
Throughout the ages of growing up we sharpen our brains with new knowledge, new short cuts, new ideas and a constantly changing perspective of people and the world. We really never realise this. Imagine a block of stone, and one side is sharpened. This is your likes, and talents and what-nots. Only one side of say multi-facial stone. With that sharpened side, you're able to get through with life. This is the case for a lot of people. Others try to hard to see the world fully and try to work on everything from all-sides. At one point they find out too much and can't stop, until one day all the dusts are blown by the wind and they lose themselves. They're a totally different person. They can't think straight. They're not gone gone.. Just different. At this stage a new stone appears and see the stone like a new level in life.
This person will have to sharpen it again, but the stone seem to be bigger, more faces, and denser. But like all stones, once corroded, cannot be regained. A person may try to sharpen their mindset, but cannot lose them. It will always be as a stone. Or sword. Either an unsharpened sword, blunt to the blow or a sleek, elven sword, swift and slices through flesh.
When we try to re-sharpen the new stone, it won't be exactly like the previous one, not the same flaws, not the same advantage. But we will soon adapt to the changes and use the new flaws and advantages to be buried within ourselves and become us.
May the sword help you through the battle this life leads on.
