The question I get asked the most, whether it is business or programming, is: how do I start?
It's easy.
Start
Stop reading. Stop doing tutorials. Stop thinking about what you are going to do. Stop talking about it. Just stop everything and start making.
I do a lot of fishing and when I was younger I would study the stream and look all around and run up and down the shore looking for where I think the fish might be. My Dad had been fishing for many many years and he didn't do that.
" Son, no fish bites the worm that isn't in the water."
Oh, I get it. One reason that my Dad catches more fish than I do, is he has his worm in the water where the fish want it!
As you jump into something and start making it, you will learn what you need to learn. The very process of making something forces you to learn what you needed to learn anyways.
Say you want to learn how to program. You could start by reading lots of books on programming and reading about all of the different programming languages and getting advice from everyone on what language and platform to write programs in, but all that will do is fill your brain with lots of information. Too much, probably.
Instead, let's say you just pick a language and a project and start writing a program to create a blog. You will start by looking up on Google how to make a blog. You will start to learn some terminology and start getting ideas. You will start writing some things and you will often be confused and have errors in your code, so you Google. Every challenge that comes your way, you search on and think about and the knowledge just comes.
The learning just takes care of itself and you will have created something.
Some projects require research and learning and it might feel like you can't 'just start'. But you can. There is always some aspect of it that you can start. Maybe it is just putting up a website that explains things or maybe you can make a prototype that plays with fake data. In fact, if you think you can't 'just start' you are probably trying to do something too complex at the beginning. The biggest thing though, is start.
You have that idea in your head as you read this. Now, stop reading and start working on it. Right now. If you are somewhere where you can't just stop what you are doing and start, then promise yourself that you will as soon as you can.
