Another piece of advice, learn to do things with your Left Hand (if you’re Left handed, then the Right one). Learn to use your non-dominant hand.
Not because being even mildly ambidextrous is a cool party trick, do it because it will make you flexible. Practice on anything, writing, painting nails, opening bottles, catching a ball.
You are developing a strength that will allow you to use a part of your body and mind most people can’t, and that can give you an advantage.
Learning to use your opposite hand isn’t actually about developing the skill, you don’t need to do anything well with it. The point of it is to make you stretch your brain in ways it hasn’t before and to problem solve. Doing this is a way to teach yourself how to think outside the box, to tackle problems from another side. When you need to use your non-dominate hand you have to slow down and be more careful. You have to think about what your doing, the next steps, flip the motion of your hand because everything is going in the opposite direction.
This is bit like the wax-on/wax-off concept in Karate Kid, it’s an indirect method to develope a skill. You take the idea of learning to do something using the wrong hand and from that experience you can take what you learned and apply it to other problems in the world. You might just be surprised how good you get and using your Left hand.
