Plans Are Worthless, Planning Is PricelessĀ¹
For almost any project, it makes sense to first conceptualize and plan before starting the actual work. Planning a few hours can save you days worth of time because it is easy to waste time on the wrong things. Therefore, I recommend you to go through the aspects mentioned above and write anything down what you imagine about your web project. You can even create a sitemap and plan individual pages by drawing wireframe diagrams with tools tools like balsamiq wireframes, figmaor penpot.
It is also worthwhile to divide the project into smaller more doable chunks and make a time plan with deadlines when sub-tasks should be done. Even if you don't end up using your elaborate plan nor any of your produced notes, sketches, wireframes or sitemap, the time spent is still not wasted. It's part of the thinking process and makes things clearer for you.
Just Do It! Start Today! Learn Project Management Along The Way
But don't overstress this part. There are all sorts of project management and requirement analysis methodologies as well as productivity techniques out there. While being knowledgeable about these can help, in the end you have to do the work yourself. So, just doing things and learning from the experience will be your greatest teacher. Occasionally, you can reflect on your process and results to refine your approach. Project management can be seen as a collaboration with others or your future self. Learning to manage a project and the time of others and yourself is very close top managing your own life. It's all about managing your own psychology and emotions to keep going and not quit. So, I'd argue that learning project management (or life management) can give your life a lot of leverage and unleash untapped potential.
Next pick a technology for building your web project. Then you can finally get your hands dirty and move one step closer to sharing the fruit of your imagination with the world!
Ā¹ The headline is a quote "Plans are worthless, planning is priceless. Spend a day making elaborate plans and then disregard them completely to make whatever you think is most compelling. Repeat monthly or quarterly" - Visakan Veerasamy
I guess his quote is somewhat derived from Winston Churchill: "Planning is crucial but a plan is useless."
Also, the notion to describe project management as a collaboration with others or your future self is from his e-book Introspect.
Here is an ironic saying by a developer who enjoys jumping straight into programming (which has a downside):
"Weeks of programming can save hours of planning"
