Break the problem you're trying to solve up into simple steps. Each step should be nothing more than a single task.

Ex. if you have a problem to solve that goes like: Must create store with products that are blue only.

Then you'd break it up like:

Create store Filter products (Blue only) Create products in store

Then when you start coding you solve nothing more than what you put down as each task.

Ex. you don't do anything more than what's required. You might think you need to create a store and stores are businesses so you need to create some business wrapper etc. but nope. You don't need that until a client comes one day and requests it. Right now all you need is a store with blue products and that is all you're going to solve.

Often when you over-engineer something then you never need the extra abstractions you created.

Though this "implement one box of the flowchart at a time" approach can lead to inflexible software due to insufficient modularization.
