Reducing cognitive load is the key. Several approaches I usually take are:
1. Make strict rules for code convention, especially naming things, and stick to that.
2. Use intermediate variables (let binding) often
3. Turn meaningful code block to a function often
4. Write Clojure specs and turn them to docstrings
In addition to that, a real REPL programming really helps to do small tests and understand the code quickly, immutable data structures with data-oriented approach and locally scoped code blocks combined with structural editor are godsend as well.
