What to do after finding your purpose?

For a long time after I got fired from my consulting job last month, I've just been drooling around jerking to Porn and not really making any progress on the one goal I had assigned to myself. I had bought a comp coding course off Udemy and really wanted to get finished on it so that I could begin working on some Google Kickstart questions (which would prepare me for coding interviews and I'd eventually find a job in Game Development or something close to it that I'd love doing and on and on.....). See I do have a clear purpose set out for me (I set it out myself). It is something that's gonna be fruitful in the long run, help me redeem my abilities to the fullest (I've always enjoyed mathematics and coding) and would help me become the person I’ve always wanted to be: financially independent, socially engaging (because w/o this fulfilling purpose I am only jerking off every day) and someone who could look forward to starting building a family (After I build enough confidence to ask someone out and start my life's dating chapter someday). However, I've only progressed by maybe 1% so far. I realised what's been suppressing me so far was my subconscious mindset that wasn't really providing me with any motivation to get things going at a good pace. I came down to this: learning is about consistency and not about motivation (do it every day).

Yesterday, I was listening to Jordan Peterson's podcast on the "The Diary Of A CEO" channel. He said, "You want to know something about yourself sit on your bed one night and say what's one thing I'm doing wrong that I know I'm doing wrong; that I could fix, that I would fix; You meditate on that you'll get an answer and it won't be one you want but it'll be the necessary one". I realised that my problem was simple: I had found my purpose but I wasn't able to 'Hard Burn' it to my heart.

I've seen people starve because of their passion, I've seen them ignore everything around them and about them because they are more passionate about learning or doing that one productive thing that gives them the highest dopamine release from achievement.

How on earth do I get that? How do I bring myself to that zone where I am giving 10-15 hours of my day (that I was previously giving to work) to do what I've already identified as my purpose?
