Easy, tiny changes in your behaviour will make the biggest impact on you in the long run! You can’t put a percentage on it but you can benefit from the compounded effects of each moment-long changes. You will never stop learning and changing your thoughts and behaviour, the question is if you make a positive switch or do something that will hinder your progress or even regresses you!
You don’t need to make a change every day just as some might advise you to do. The most important thing is to practice the change that you had made earlier! Practice, solidify and check. Make it a life-long habit if it works, or ditch it if it doesn’t and try something different. So it is important to check after a week, a month or even after six months if you still benefit from it. You can adopt another change in a couple of days or as you feel comfortable with, but please do not pressure yourself to make a change rigidly daily or weekly!
Be kind to yourself because you are your own best teacher if and when you can be honest with yourself without any judgement that might come from your religion or culture. They are just giving you a framework to start with but they can’t give you the end result! you work on that regularly.
You educate yourself, check different takes on one idea and keep yourself free of biases. Do not be afraid of introducing and debating new ideas and ways of thinking! It just like working all day and then taking a refreshing shower at the end of the day. Let new ideas in, debate them, confront different theories and come up with your own conclusion! That is what educated intelligent people do. They don’t take brand new fashionable ideas for granted but they also do not fall into the trap of old ideas, teachings and theories. These old teachings were thought out and taught to the contemporaries and not a thousand-year or two-thousand-year far from their generation, You need to sort out what you can use today and what does not apply. Please do not make the mistake of taking a teaching word-for-word without debating over it or thinking it through.
If it helps, you could imagine yourself living in the ear it was written in. You might want to be part of the 90% of people to be accurate, but you could rise to the top 3% who could read, write and debate the idea then. For example two thousand years ago in the entire Roman empire 90% of people could not write at all and only about 3% of people could read as well as write. So imagine how many people had the education to compare one idea with another and have a meaningful debate over it!
Now come back to the present time and think that in the first and second world countries 99% of people were taught how to dead and write. So now it would be up to them to educate themselves because they got the basic tools already!
The secret is that you build up your knowledge block by block and then apply critical thinking so you can find similar and opposite ideas that you can compare them to. Leave your biases behind and build your knowledge day by day to empower yourself!
