My suggestion would be to set aside a reasonable amount of money to be able to continue a normal lifestyle if something should ever occur and then try to figure out how you can habe the most positive impact in the world. There is a movement called effective altruism (EA) which specializes on the topic of how to do the most good with the resources you have. For example, there ks the website 80000hours.org which does research into the worlds most pressing problems and how you can use your career to solve them. For me, the most interesting thing about EA is that it combines a challenge to develop yourself with a meaningful goal and a supportive community to help you along. You could certainly contact 80000hours to get personalized recommendations if you tell them you have say 7m available. Other organizations which may be interesting to you are: givingwhatwecan.org; founderspledge.org; or more generally effectivealtruism.org. You could also ask more specific questions here and I will see what I can do for you :)
