It is important to do something you like doing, not just to start doing something you think will earn money. You will be working long hours, initially for little pay. You will only start earning well when you have established yourself and have become known for what you do. If you have a creative skill or talent, or you are have a lot of good knowledge about something, you can teach others, or sell your services, or market your products. Being self employed is very rewarding and can make you money if you provide a good service. You need to know how to promote yourself effectively and get yourself a good reputation.
