# The Pitfalls of Over-Reliance on Code Blueprints

Developers often try to use blueprints as a shortcut. This is a mistake. If you don’t go through the process of solving the problem and translating your ideas into code, you will not have understood the solution and internalized it.

Every successful program you write is more than a solution to a current problem. It is a potential source of analogies to solve future problems. The more you rely on blueprints now, the more you will have to rely on it in the future.

If we recognize analogy early enough, we can avoid most of the work of the problem by translating our solution from the first problem rather than creating a new solution. Most analogies in problem solving won’t be direct, but they will happen with increasing frequency. You will begin to recognize them more after you are on the lookout for them.

## The Importance of Deep Understanding and Analogy in Programming

It’s tempting for many developers, especially those new to the field, to use code blueprints or templates as a way to quickly solve problems. While these can be helpful tools, particularly when learning a new technology or language, over-reliance on them can stifle the development of critical problem-solving skills. Here’s why:

**Understanding and Internalization:**When you use a blueprint, you’re essentially using a pre-packaged solution. This might solve your immediate problem, but it doesn’t necessarily help you understand why the solution works or how it could be adapted to fit a different but related problem. Each problem you encounter is an opportunity to deepen your understanding of programming principles and your command of the language you’re working in. If you lean too heavily on blueprints, you miss these learning opportunities.For example, if you’re using a blueprint to solve a sorting problem, you might successfully sort your list, but you might not learn anything about how different sorting algorithms work and why one might be more efficient than another for your particular data set.

**Analogies and Problem-Solving Skills:**Solving programming problems is often more about thinking creatively and finding analogies to known problems than it is about writing syntax. If you always start from a blueprint, you don’t get to exercise those analogy-finding muscles.As an illustration, suppose you’ve previously written a program to find the shortest path between two points on a graph. Now you’re faced with a problem involving optimal resource allocation. If you’ve internalized the principles behind the shortest path problem, you might recognize that this new problem is also about finding an optimal solution within a network of possibilities, and thus apply the same kind of reasoning or algorithm (perhaps a modification of Dijkstra’s algorithm).

**Adaptability:**No two problems are exactly alike. Even if you find a blueprint that seems to fit your current problem, there’s a good chance you’ll need to modify it in some way. If you don’t understand the logic behind the blueprint, making the necessary modifications can be tricky.For instance, maybe you’re using a blueprint for a web scraping script, but the website you’re working with has a slightly different HTML structure than the one the blueprint was designed for. If you understand how the script works, it’s a simple matter to adjust the XPath expressions or BeautifulSoup commands. If not, you might find yourself stuck.

In summary, while code blueprints can be valuable learning aids and useful for accelerating certain aspects of development, they’re no substitute for a deep understanding of the underlying problem-solving principles. As you gain experience in coding, you’ll find that you start to recognize common patterns and can apply solutions from previous problems to new ones. This is a more sustainable and rewarding way to improve your programming skills over the long term.
