I think you've answered your own question - be less meticulous. Oh, and memorise less.
A good programmer knows where their knowledge boundaries are. For example, if you're working in JavaScript, you probably don't need to know bit-shifting.
A good programmer doesn't know every feature; they know where to go to find that information. They know how to read the manual of an unfamiliar feature.
The most important thing you can do is do practical work. Build a website. Try new things. Look up how to implement something and then do it yourself. Find a project that interests you - like building your own website - that'll stave off the fatigue.
You don't need to memorise how to implement a linked-list - you need experience in building.
Good luck.
Huge if true.
