I worked for 2 companies in 2 different continent with total different mentalities but what they have in common that they both don't care about programmers... Programmer is usually associated with the bottom level of companies... They are usually associated with beginners and have the smallest wages... while Project Managers, architects etc... usually take more money and do less work...

I have been working for almost 4 years now and I have nearly the same feeling as you... Switching between projects... trying all the possible programming languages... C, C#, php, ASP.NET, WinForm, C++, Python, VB.NET, VBA... and a lot more was some of the languages I worked with... Since the moment your superiors discover that you can make it with any language that they give you, they will tag you as a "good" resource and give you all the dirty job...

I haven't neither got a mentor to guide me thorough my career... and like many who wrote here... I only find my satisfaction when I do make my personal projects... but unfortunately usually the long hours of work didn't let me to make some serious work...

In conclusion, I will spend some months lost till I decide like the majority of passionate developer to give up and take a merely boring architect post to get more cash
