One of the first things to invest in as a beginner is your financial literacy. Read a few books and listen to a few podcasts on the basics of investing. Then once you have a basic understanding of investments and the difference between gambling and investing, you can start to look at investing in the great companies of the world. The best place to start is in your company pension scheme followed by tax efficient investment accounts. Index funds are the cheapest and simplest way to get started in investing.
