Everyday write down what you had learnt in this day, And everyday read what you had written and learnt in the previous days.

1-you will always find something you had learnt
2-you will always remember what you had learnt and use it in your future life
3-after a week read what you had learnt in the previous week and evaluate yourself and how you got improved
4-repeat: do the same process

Finally you don't have to write down as your subconscious mind will easily do the process because you installed this feature in it.
So you will automatically learn everyday and improve without doing much effort.

Once you work on your subconscious mind you will be able to learn more and more
