Why am I becoming a professional software developer?

Why do you want to learn to code? I want to prove myself I can improve and develop a great skill like coding/programming. I want to learn for me and my loved ones, I’m not necessarily trying to land a fancy job on big tech, I’m more inclined to bring development to the region I’m at if possible and even if it is just in a very microscopic way, impact my family and community through technology.
How much time do I commit to learning to code every day? 2-4 hours daily.
If I knew everything about coding, what would I like to build with my skills? I would like to build first a Web page for my small business, being able to cover every aspect including online sales would be amazing and a dream come true. Additionally, I would like to develop a software that can help me with automation for indoor plant grow rooms.
