Has it worked for you? How?
I kept them simple and achievable. For example "lift weights 3 times a week".
Next step was to pick one at a time and schedule them. For example "MWF right after work". This helps make them a habit instead of a constant battle with your willpower.
Don't punish yourself for getting off track. Just get back to it. Eventually it will become part of who you are and you'll rarely get off track.
Create the habit. Results will follow.
Also, I think it's sometimes hard to recognize whether a goal you have is indeed your own goal; or rather a goal "forced" onto you by your social circle or family.

But others need self created structure, and reminders.
Sometimes planning is not useful beyond just remembering what you planned.
Writing down is perfect if you need to focus on something else and dont want your brain power used for remembering.
1. knowing the right thing to do
2. doing it
Does planning help with either? Surprisingly it helps with the second more than the first. For the first, things like reading and finding a mentor helps more.
Often it's iterative too. Doing a thing often helps you figure out what you shouldn't be doing.
Say you wanted to find the perfect spouse. You don't do this by listing characteristics of that person. Nor do you do the research and hire a marriage expert to figure out the perfect spouse. You do it by dating. You reasssess whether you could be dating better people.

But if you have plans and execute them, you invite the luck in
At least this is my copium
discipline == execution
ideas are worthless, its all about the execution
