Some tips from me:
- Take a nice holiday - Don't rush into investing. Take some time to think about what you want to do. - If you invest in stocks, do it in a staged plan. Resist the urge to sell when it's going down, and the urge to buy when it's going up. (I could not resist buying when it went up beginning January this year). Start with small amounts first. Be there for the long run (don't sell/buy all the time). Be prepared that you can go up/down a lot in one day. - Rather invest in index funds then specific stocks - Don't invest everything in one type. Don't just use 1 broker. Stay away from leveraged, turbos, bitcoins, etc... - Be careful about tax impacts on your decisions, depending on where you live - Be careful about private investments. Only invest into something which you understand and have knowledge of and can help and make it possible. Only take market risk, and not the execution risk. (I for instance have not yet done any investments so far) - I put some of my money in hedge funds (Millenium, etc..) through a private bank (additional yearly fee + performance fee).
And: - Think about what you would like to do. For me that's starting a new company (since I already did that before and succeeded). If you like your job, then stay.
