Sounds like you've already taken the biggest and hardest step; which is to simply initiate the change.
My #1 piece of advice, while you're setting goals and scheduling activities, is to understand the organic rhythm and cadence of growth for each goal.
Work brings an inherent cadence of 9am-5pm, Mon-Fri and success is often calibrated every week/sprint/quarter.
But learning guitar, body building, and understanding new programming languages each have their own organic cadence and process for achieving mastery.
Sometimes taking a break from learning something new and simply reflecting is better than grinding away for 5 hrs per day, as that pattern tends to reinforce bad habits rather than develop new and better habits.
