First of all Its great to set goals and have roadmap to make it happen, but in your plan there is some flaws. First of all Udemy gives only some basic thing like 2+2 and 2*2 , yes you learn something but just some ropes. Second problem is your roadmap availeble right now for basic things, after you finish this course you need to build some project and work on your skills again and again, so every 1-2 months you need to update your roadmap from scratch and it will be hard to be satill motivated. For me its hardest part then you learned basic things, and made some first projects to keep going and increase difficulty, I hope you will keep doing and we will see some your programming diary in steem, but for now this your roadmap is just first baby steps. It will be interesting to follow your blog
