q We Cannot Solve Our Problems With The Same Thinking We Used When We Created Them.

h2 How we usually find solutions and why this is problematic?
ul
li We search for code example instead of algorithms.
li We copy and paste and do testing on trial&error principle.
li We don't take enough time to properly understand problem we a re trying to solve.
li Brute force solutions we make are usually not optimized
