What are some ways for young people for have been working for not too long ( i.e. less than 5 years) to learn how to invest ?

First, read up about etfs. In a nutshell, they are funds that hold stocks that make up an index. They are generally less risky than buying individual stocks.

If you want to achieve better than market returns, learn how to perform fundamental analysis and technical analysis. This will provide you with the skills to pick individual stocks sensibly.

Once you are more experienced and have more capital, you may want to venture into fixed income products, derivatives (e.g. options, futures) and alternative investments (e.g. commodities, property)

For me, i do this by

1. Investment books (what metrics to look out for, build your mindset, learn people mistake)

2. read blogs (why they choose certain stock, what is their holding/portfolio)

3. subscribe to services to give you more analysis or easier management like stock cafe or stock report analysis, can also be screener

4. paper trade to get some hand on experience.

5. throw in some real cash to buy real stock and check on the mindset.

Books are your friends. Read more.

The singapore libraries are full of great investment books, the problem is having time to read them.

probably spend less time on netflix and more time on books

Read more investing books, forums (hardwarezone, seedly, sharejunction), financial blogs, and if you are willing to, join an investment course. But I would advise you to focus on books & forums first before deciding to join the course - build up the initial knowledge first through reading (a lot)!
