The safest place to invest is to invest in yourself. Get a good education, if you never had a chance to go to college, you can join an online campus. Once you have the degree in your chosen field, consider learning skills. You should focus on gaining technical skills. These days knowledge and skills in information technology help. Then only consider investing in a business. Start with your own business, perhaps a website, a blog, youtube channel, a mobile app, anything that can make you successful.
