There is a common mistake made about practical things and theoretical things. Most people I know think that theory is boring, unneccesary, and useless, while practical matters are good because they are useful to them and give them something. This classification of practical and theoretical is incorrect. Both are needed in most any situation for several reasons.
The first reason is that practice is developped by theory, or atleast has an inherent theory. This is universally true for any practical matter, as far as I am aware of. What this means is that practice is an extension of theory.
Because of this, pratice is better when theory is incorporated into it. The obvious example of this is empirically developped practices, which only account for what has been discovered during practice so far. Essentially this is not thorough enough to make an accurate practice without often significant experience and luck. Often it might not even be possible to discover how to properly do something practically without a significant amount of theory. An example of this is high end technology which requires so much theory to create that any attempt to simple do it without theory would be close to impossible since they’d essentially be teaching themselves theory from the ground up.
The third reason for this is that a practice without theory is just mechanical. If you know what to do but you don’t know why you’re doing it, then you’re limited to only being able to do a certain amount of things. If any problem comes up that your practice hasn’t accounted for, your practice would not work. Someone who understands how and why the practice works would be able to adjust and develop new practices. This is the difference between a mechanic and an engineer, although ussually mechanics are fairly well trained for what they’re expected to do, but aren’t always able to go into new fields.
Finally, theory is not boring. Some people may think this because they have a false idea that school is meant to teach you how to live life, and therefore assume that what you learn is supposed to be practical so that you can use it sometime in your life. Often students ask “When am I going to use this in my life?”. This question assumes that you’re only learning directly applicable knowledge, practical knowledge. Since they assume that they’re going to be receiving practical knowledge, and that they’re being trained to live in the “real world”, it’s natural that they would find theoretical knowledge as boring. If students understood that they’re not being trained, but educated, then this would be less of an issue.
Also, learning, and hence learning both practical and theoretical knwoledge, is fun. There is a thirst for knowledge and interest in learning that people that appreciate theory have. It’s why you go to school and are interested to learn about history, because it’s like listening to a story, or learn about physics because it explains the most fundamental ways that everything around you works, or just simply discover that there are shiny new fields that you’ve ever even heard of.
Learning is fundamental, useful, and interesting. Practical knowledge is necessary and can sometimes be interesting, theoretical knowledge is also necessary, very useful, and interesting if you have been shown why it’s interesting and therefore can appreciate it.
