I think most ppl have no problems with micro focus because it’s required to do the job.
Macro focus is harder because it requires a series of tasks aligned for one purpose. Think sets instead of reps during weight training. Or even think workout schedule as opposed to workout session.
The challenges with long term goals are consistency and balance (You don’t want to overdo it and risk premature burnout). Also, it’s about being true to yourself and realizing life goals often change and so it is wise to re-evaluate often to make sure you’re moving in the right direction.
