Trying to catch up with Java is a hard game to play.
The one you will lose, as Java has no limits and you only have 24hrs per day.

That is why I want to share these 5 absolutely free ways to become a recognized Java expert in the community, while learning only those parts of Java which you really need.

You will land a job, a very good one, if you want it and if you follow these ideas. There are other ways too, but these ones are based on my personal experience and advice from Java Champions.

There also will be a gift from me, in the very end.

There are so many amazing Java OSS projects. Why don’t people contribute?
Well, the main reason is - people think OSS contributions are hard and you have to be an expert.

That is where I completely disagree. Literally everybody, of any IT skills, can contribute.

Still not sure? Post your questions below, or oin #TWOSS and help us to build bridges between people and their dreams. Using OpenSource.
