If i do able to take that course then it would really be relevant on whats the current job offerings as of todays which is mostly attached or in related in digital aspect like programming
digital arts designing etc. which could potentially give out that income or salary which is more than that you could earn when you do apply yourself on a day job.
Most of the time these are the skills which are really that needed and it would really take a while for you to learn or having mastery on it.
Don't let anything stop you from following your passion no matter what age you are. Nowadays, it is almost never too late for you to pursue the career you want. For instance, I am 30+ years old. People my age are supposed to be settled into the middle-class in their 40s but I am not there yet, yet have almost put my roots there. That is because I knew what I want from my life. I did not just have an interest in pursuing a degree in Information Technology, I put a lot of effort to make sure I got a good chance of excelling in it. I have always been passionate about the field and so far in life I have always strived to do everything to make my dream come true. I can proudly say that my way of pursuing my interest has got me somewhere, that is to say, I am in a career that I love so much that my job has always kept me satisfied.
