I love PHP and C# languages and i want to be excellent in both. I like to develop PHP applications using MySQL, Nginx, Memcached and so on technologies. I also like ASP.NET MVC stack and think it's great tools. But each technology requires a lot of time to master it. The same is true for C# web stack - there is a huge amount of things to be mastered like Azure, LINQ, Entity Framework ets. Mastering PHP means knowing how it works under the hood. Mastering C# means knowing CLR implementations on a deep level, knowing MSIL etc/ Where to get time for all this? Maybe this is "jack of all trades"? What can you advice?
