So exactly how do you do anything?
You do it by applying sufficient regular focused attention. Let’s look at the parts of that.
You have to put the hours in. It takes time, and that means making time for it. It also means that time which should be allocated for it isn’t used for doing other stuff instead. It’s good practice at the beginning of each day to write a list of the most important things that you want to have done that day. Then check at the end of the day that you actually have done those things and take remedial action if you haven’t.
Decide what frequency is appropriate for the project and keep to it. Usually, but by no means always, daily is best. And usually, but not always, it’s best to do it early in the day.
Just generally messing around in an unfocused way achieves little. if you’re learning a skill you should be focusing on what needs practice . If you’re building something, focus on what needs doing next. As a general rule, get the skills right before you start applying them.
“Time management” isn’t really about managing time. It’s about managing your attention. Anything that you give your attention to will change and develop. But remember your attention is finite - allocate it carefully.
