Consistency is the Key

Consistency is the hardest part of golf.
It is not possible for any human, Tiger Woods included, to hit the golf ball perfectly 100% of the time.

What good golfers can do however is consistently hit the ball very well most of the time, and near perfectly quite a lot of the time.

It is this consistency that sets them apart and even those at the top of their game have days when they don't get their shots right enough of the time.

There is only one thing that can really help any golfer get more consistency and that is through practice.

But there is another matter needing to be addressed when talking about consistency and golf and that is - Consistently bad shots.

The more you do anything consistently the more it will become natural behavior and this applies to poor technique too.

The sooner you address poor golf techniques, the sooner you will be able to practice the correct methods that will replace them and make those actions second nature.

This is why it is recommended that everyone should get professional instruction before learning bad techniques that will need to be relearned at a later time.

I would even go to the extent of advising a newcomer to the sport to have lessons before ever attempting to play a round.
Or alternatively, learn how to use one club well, probably the 7 iron, and play a whole round, or nine holes, using only the 7 iron and a putter.

I knew of one player who made dramatic improvements to his game by using this technique and he had been playing for years.
He started playing golf with only the 7-iron and his putter, until he perfected his swing, and then introduced other clubs one at a time.

After getting his swing right with the 7-iron, mastering the other clubs was relatively simple.
