I am over 50 now, and still most of mythe ideas and knowledge that I have today were acquired because I read a lot when I was young.

There is a big difference in confidence between those who read a lot and those who does not.

It is no exaggeration to say what you think aboutof your life and how you live depend a great deal on what you read when you are young.

addinf "a great deal" makes it clear that the reading has a big impact. Not absolutely necessary, but it helps sound natural (I think) and makes your intention (of a big impact) clear
