Straight out from the Planning mess!
Your natural approach to not realizing your plans on time in the past has been to put in more effort, and try to capture everything in one go and committing to it upfront.
Here such proposals are unquestionably attractive on paper, but they are only that.
The better your plans look on paper, the better they get in terms of speculation and obscurity.
Indeed, at that point, they appear terrific only because they lack a link with reality and unable to empathize uncertainty in the long run.
When you are so engrossed in your planning and plans, you lose sight of all you should be learning otherwise.
Remember, ignoring the increase in complexity and paying less attention to the learnings, are no better than trying to fish as a novice in unclear waters.
