Rene: Great question. I often thought about what I would tell my younger self.
I enjoy reading. Therefore I would recommend 2 books that answered your question.
(1) The 7 Habits of Highly Effective People by Stephen R. Covey.
This self-help book provides timeless principles that build one's character. I am still using the principle outlined in that book today.
(2) How to Win Friends and Influence People by Dale Carnegie
When I met with college hires (new employees just graduated from college and joined the company), I said to myself, you will be successful quicker at the work place if you practice the habits from "How to Win Friends and Influence People", instead of complaining about the things not going your way. Some of them would listen to me. But others will ignore me and continue complaint.
This professional recommends the following next steps:
- Read "The 7 Habits of Highly Effective People"
- Read "How to Win Friends and Influence People"
