I am a graphic designer for 3 years now, once a 25 years experience graphic designer told me "I learned, what he learned in 7 years, in just 1.5 years" and all i was following these tips through out the year, now here we go.........

• Every job required some sort of mindset, designers needs time management, police need calmness, you must know the mindset of what you want to become....how they think, how they handle situations, if you want to become a CA then know what type of mindset a 10 years experience CA have. To do this you must listen to there Podcasts, meet them - vibe with their aura, etc In short - Know the phycology of that job

Knowing the history of anything increases your respect for that thing, if you simply say "India got independence in 1947" People be like "ohhh...that's good" but if you can elaborate it to them, tell them about Jallianwala Bagh, Mahatma Gandhi etc. Then they will understand how important this event was, just like that, knowing the history of your subject will increase its respect and importance in your eyes, what happened in history that leads to the invention of that subject, its Contribution to human society, you will come to know of many great names, who may becomes your mentor

Don't underestimate the power of imagination everything in this world got created twice once in mind then in the physical world. Imagine yourself having a conversation with your mentor ( basically have a conversation with yourself, imagining it with mentor is just one way) comes up with your own concepts, by questioning everything even if you know what it is still question it and comes up with different uses and concepts of same thing 

Knowledge disappears, if it is not trapped in books, make a habit of documenting everything you have learned throughout the day

It's also a good way to see where you were and where you are now (how far you've come)
