Affiliate Marketing Secrets

Well, I’m 16 years old and I have been interested in the whole concept of buying and selling shares and how it works and the factors that affect its price.
I wanted to start learning young so, when I am actually old enough I have a really solid foundation.
Are there any books you recommend I read first and foremost.
For a first book I want one that explains everything in general I was looking at “Investing in Shares for Dummies by David Stevenson” just to start with.
Once I have the fundamental knowledge I would move on to something more hefty.
Also have you just got any genuine tips?

I started a new job about 8 mths ago. Educational/school counsellor. At first it was hard, but then I found my niche and the bosses went out of their way to say how much they liked my work. (they had an alterior motive, too I think since the previous person in my job went on stress leave because of them, and the wanted to prove they could look after me). But nevertheless things were good.After coming back from summer hols, I’m not sure but things are not so good. In particular something has come from left field. A student has had some major incidents (they are fine now though) and I have not been working on the case – information was not passed on to me very well and I didn’t pick up the gravity of the situation. After the handover I wasnt’ involved in the case, and I wasn’t aware of the importance of the case. Information about the case was passed to my supervisor from the outside agency that dealt with the student, and she came to help us deal with it. Embarrassingly, she told me in front of my on-site bosses what I had to do and taht it was really important. I feel so caught out. I even said to my bosses that I didn’t know much about the case – I feel so embarrassed as it would have seemed like i was ducking for cover. My supervisor is showing she doesn’t trust my work by questioning me on other cases too. I had answers but I feel under scrutiny. It’s as good as a reprimand. I feel so shown up – like my facade is falling down – my reputation changing to that of unreliability.
I feel like I’ve lost my reputation 🙁 So hard to stop ruminating over this and get back on the front foot 🙁
I work in a very high stress job with fairly decent pay – has anyone else been through this? Tips on digging back in despite worries and doubts
