I am happy to reformulate my response by deleting "business" from it.
If you are looking to make a change in your life - especially when looking to make a decision while under duress - it can easy to assume that any change will result in a better situation, it can also be easy to hesitate due to uncertainty and fear. Here are some questions I would be asking in my "plan":
1. what do I want to do professionally? What do I want to be doing in 6 months, 12 months, 2 years.
2. what means would I have to support myself? Am I burning capital, accumulating debt, or do I have to tolerate some crappy job to pay the rent?
3. if I am looking to first develop ideas to start a business, how long can I continue to support myself as identified in 2?
4. I'm interested in a software development, but have identified that I need to grow my own technical skills. Do I know how I'll do this? How long do I expect to be in a learning phase before being able to capitalise on these skills? Can the courses I am currently doing help provide me with skills (sounds like science/engineering?) - at what cost?
5. what is my risk profile? Am I young with little/no debt, and no wife/kids? Therefore do I need a backup, or can I just get on with it?
Bottom line for me is: if you can analyse your situation objectively, and see where you want to go and what you need to do to get there (questions like 1 - 5) then back yourself.
