Jack of all trades, master of none

"Jack of all trades, master of none" is an old saying, meaning that one is competent in a lot of things, but master of none. Such a person is also called a polymath or a renaissance man. A prime example of this personality is Leonardo da Vinci.

I think I am moving into becoming a polymath - a jack of all trades - and I have mostly done this out of my own will. I don't want to specialize, I want to be really good at a lot of things.

The thing I want to do is to build systems that users want to use and my dream is to build something that changes the world. In order to do so, I must master a lot of skills, namely:

• knowing what users want, understanding users and their needs [that's why I find psychology really interesting]
• building useable applications, creating usable designs
• creating aesthetically pleasing designs
• building the interface using JavaScript, CSS, HTML etc.
• knowing how to scale an application, that's one of the reasons I built lightcloud
• becoming a DBA
• understanding business to know how to develop an idea and make it profitable. todoist is profitable
• understanding analytics, viral growth
• coding in Python, C, Java etc.

You can do these things with a team. But mastering these things yourself makes you much more powerful. Independent. Free.

A lot of these things can also be combined and the more you master, the more powerful you are and the probability of success becomes much higher.
